Hemophilia is an X-linked trait caused by the allele h. About 1 in 10,000 males (0.0001) has hemophilia. The frequency of the h allele in males is therefore
.
Answer : 0.0001
Explanation:
Since males only have 1 X chromosome, the number of males with h alleles should be equal to number of males with Haemophilia and therefore the frequency of males with Haemophilia must be equal to the frequency of h alleles on X chromosome.

What happens if a cell is unable to divide by mitosis
Answer:
When this happens, sometimes the cell commits a special type death is called apoptosis. Apoptosis, otherwise known as programmed cell death, ensures that if mitosis goes wrong and cannot be fixed, the cell does not continue to divide, as this would lead to the production of mutant cells that might cause problems.

Peter is 20 months old, weighs 28 lb, and he wants to eat the same food his older brothers do. No baby food for him; he is a big boy now! His mother is worried that this might not be an appropriate diet for a toddler and asked you, the nutrition student, to check it out. Be prepared for a challenge! It’s not easy to think about all the elements that make a healthful diet at the same time. You have to think about kilocalories, Acceptable Macronutrient Distribution Ranges (AMDR, which by the way are different for toddlers than for adults and adolescents), and watch iron (the most common dietary deficit in toddlers) and fiber intake. And that’s just the beginning. Adequate intake of fluids and electrolytes is also critical for a toddler’s health. Is your head spinning already? Let’s simplify the job by approaching each of the recommended Daily Values separately.
A balanced diet helps to prevent malnutrition in all of its manifestations as well as a number of noncommunicable diseases (NCDs) and illnesses throughout the life course.
What is Diet?However, there has been a change in dietary patterns as a result of increased production of processed foods, growing urbanization, and changing lifestyles.
Nowadays, individuals eat more meals that are heavy in calories, fats, free sugars, and sodium/sodium, and many people eat insufficient amounts of fruit, vegetables, and other dietary fiber-rich foods like whole grains.
Depending on individual characteristics (such as age, gender, lifestyle, and level of physical activity), cultural context, regionally accessible foods, and dietary habits, a diversified, balanced, and healthy diet will take on different compositions.
Therefore, A balanced diet helps to prevent malnutrition in all of its manifestations as well as a number of noncommunicable diseases (NCDs) and illnesses throughout the life course.

muscle strains are most often located:
on the surface of the muscle.
under the surface of the muscle.
in the middle section of the muscle.
where the muscle meets the tendon.
Answer:
where the muscle meets the tendon.
Explanation:
I put the answer above and I got it wrong so this is the correct answer!!
:)
Muscle strains are most often located where the muscle meets the tendon. Therefore, the correct option is D.
Stretching or tearing of muscle fibers can occur when a muscle stretches or contracts suddenly or excessively. This often occurs at the musculotendinous junction, where the muscle attaches to the tendon. The area where the tendon meets the muscle is particularly prone to strain, because of the significant stress and tension that occurs there during muscle contractions and movements. Depending on the degree of muscle fiber damage, the intensity of a strain can range from mild to severe.
Therefore, the correct option is D.

Answer:
45 cells would be in the interphase
In the nuclei of 100 skin cells. The number of skin cells would be in interphase is 45.
What are cells?Cells are the key unit of living organisms. The cell divides into many cells through the process of cell division.
Prokaryotic cells are the primitive type of cells that are present only in unicellular organisms, and they do not undergo cell division. These cells do not have true cell organelles and a nucleus, in that DNA is present in coil form in the cytoplasm. They contain ribosomes the organisms are bacteria that contain prokaryotic cells.
Eukaryotic cells are higher cells that contain cell organelles they have to perform various complex functions of large organisms. They have a nucleus which contains DNA or genetic material, it does not have flagella.
Therefore, the number of skin cells in the interphase is 45 cells.

Assume for the purposes of this problem that the order of and distances between three linked genes are the following: unc-32 10mu vab-7 20mu dpy-17 What is the probability of obtaining a phenotypic unc-32 vab-7 offspring from a cross between a heterozygous fly(unc-32 vab-7 dpy-17/ ) and the triple recessive nematode
From the distances between genes and their order, it is possible to get recombination frequencies per region (simple and double recombination frequencies). The probability of obtaining a unc-32 vab-7 + offspring is 0.09 = 9%.
---------------------
We are usually asked to get the order of genes in a chromosome. To do so, we need to get the distances between genes. And to get distances between genes, we need to get their recombination frequency.
When three genes are involved, we get the distances by taking the recombination frequency, P, per region.
We talk about regions, R, when we are making reference to the space between two genes.
Gene 1 -----(R1)----- Gene 2 --------(R2)------ Gene 3
P1 P2
P1 = recombination frequency between Gene 1 and Gene 2P2 = recombination frequency between Gene 2 and Gene 3⇒ P1 = (SR + DR) / N
⇒ P2 = (SR + DR)/ N
Where:
SR is the number of simple recombinants in each region, DR is the number of double recombinants in each region, and N is the total number of individuals.The genetic distance will result from multiplying that frequency by 100 and expressing it in map units (MU). One centiMorgan (cM) equals one map unit (MU).
In the exposed problem, we need to do the inverse way. We already have the order and distances between genes, and we need to get the recombination frequency, P.
We know that the order of genes is as follows,
unc-32 ------------- vab-7----------------- dpy-17
Distances are:
Region 1 = 10 MURegion 2 = 20 MUWe need to get the probability of obtaining a phenotypic unc-32 vab-7 + offspring from a cross between a heter0zyg0us fly (unc-32 vab-7 dpy-17/ + + + ) and the triple recessive nematode (unc-32 vab-7 dpy-17 / unc-32 vab-7 dpy-17).
Cross:
unc-32 vab-7 dpy-17 / + + + x unc-32 vab-7 dpy-17 / unc-32 vab-7 dpy-17
To get the genotype unc-32 vab-7 + , a simple recombination, SR, must occur in region 2.
So we need to get the simple recombination frequency in Region 2.
To do so, first we need to clear the following equation
Distance between vab-7 dpy-17 = P2 x 100 = 20 MU
20MU = P2 x 100
P2 = 20 / 100
P2 = 0.2
The recombination frequency in region 2 (P2) is 0.2.
Now, we need to get the simple recombination frequency in this region.
P2 = (SR + DR) / N
P2 = Simple recombinants Frequency + Double recombinants Frequency
R1 = 10 MUR2 = 20 MUDouble recombinants Frequency = 10% x 20% = 0.1 x 0.2 = 0.02P2 = Simple recombinants Frequency + Double recombinants Frequency
0.2 = Simple recombinants Frequency + 0.02
Clearing the equation,
Simple recombinants Frequency = 0.2 - 0.02 = 0.18
Simple recombinant frequency in region 2 will produce the following two chromosomes,
unc-32 vab-7 ++ + dpy-17So half of this frequency will produce one chromosome, and the other half will produce the other chromosome.
unc-32 vab-7 + ⇒ 0.09+ + dpy-17 ⇒ 0.09So, the probability of obtaining a phenotypic unc-32 vab-7 + offspring is 0.09 = 9%.

Plants lose __ % water to transpiration resulting in 10% increase in atmospheric water vapor which increases relative humidity and chance of precipitation.
A: 90
B: 10
C: 100
D: 45
Answer: A
Explanation: Transpiration is the loss of water from the plant through evaporation at the leaf surface. It is the main driver of water movement in the xylem. Transpiration is caused by the evaporation of water at the leaf–atmosphere interface. Up to 90 percent of the water taken up by roots may be lost through transpiration as only a small amount of that water is used for growth and metabolism.
