In mice, the allele for black coat color (B) is dominant over the brown allele (b). Two heterozygous mice are mated, and produce the following offspring:
20 black
4 brown
What is the EXPECTED FREQUENCY of black and brown mice in the offspring from this cross?
a. 5 black: 1 brown
b. 3 black: 1 brown
c. 2 black: 1 brown
d. 1 black: 3 brown
Answers
Answer:
a. 5 black: 1 brown
Explanation:
This question involves a gene coding for coat color in mice. The allele for black coat color (B) is dominant over the brown allele (b). This means a mouse that is heterozygous for the Gene will have a black coat color.
According to this question, two heterozygous mice are mated i.e. Bb × Bb to produce the following offspring: 20 black mice and 4 brown mice.
Based on this result, the EXPECTED FREQUENCY of black and brown mice in the offsprings can be calculated;
20 black ÷ 4 = 5
4 brown ÷ 4 = 1
The expected frequency of black to brown is 5:1.

Chromosome structure can be microscopically observed best during.
a. telophase b. anaphase c. prophase d. metaphase 1
Answers
Answer: chromatin condenses into chromosomes and can be best observed in prophase.
Explanation: chromosomes can’t be visualised by a light microscope except during cell division (mitosis or meiosis). The individual chromosomes become visible as the chromatin is wound tightly and are most clealry seen in late prophase.

Most of the GMO crops grown today were developed to help farmers prevent crop loss. The three most common traits found in GMO crops are: (1) resistance to insect damage; (2) tolerance to herbicides; and (3) resistance to plant viruses. Let's consider #2, tolerance to herbicides: farmers using herbicide-tolerant crops do not need to till the soil, which they normally do to get rid of weeds. Which of these is NOT a positive environmental and economic impacts of this GMO trait?
A) Reduced soil tillage results in less soil erosion.
B) No-till planting results in lower fuel and labor costs.
C) No-till planting results in higher crop yields per acre.

When a population reaches carrying capacity.
What is Natural selection?
An evolutionary mechanism is natural selection. Environment-adapted organisms have a higher chance of surviving and dispersing the genes that contributed to their success. Over time, this mechanism leads to the evolution and divergence of species.
One way to explain the millions of species that have existed on Earth is through natural selection.
The idea of evolution by natural selection is credited to Charles Darwin (1809-1882) and Alfred Russel Wallace (1823-1913), who co-wrote a paper on it in 1858.
Therefore, When a population reaches carrying capacity.

When a whale dies, its body often falls
to the seafloor. The whale's body then becomes food and shelter for organisms in the deep sea. This is called a whale fall. A deep-sea whale
fall might support 200 different species for as long as 10 years! Larger species, such as Atlantic hagfish, are the first to arrive to feed
on the whale flesh. Later, smaller species of snails and crustaceans come to eat the remaining flesh. Worms burrow into the sand beneath
the whale body, and bacteria feed on the whale bones.
At a deep-sea whale fall, the Atlantic hagfish, the crustaceans, and the sand make up which
of the following? Select all that apply.
A. a population
B. part of a community
C. part of an ecosystem

Which statement is accurate about dominant alleles? (1 point)
O They are expressed whenever present.
O They are indicated by lowercase letters.
O They result in the trait of shortness in pea plants.
O They are expressed only when a recessive allele is not present.
Answers
Answer: I believe it would be A "They are expressed whenever present."
Explanation: Dominant alleles always show up, in the F1 generation the recessive allele are masked.
The statement is accurate about dominant alleles is they are expressed whenever present. Hence option a is correct.
What are dominant alleles?Dominant alleles are defined as a gene variant that, despite the presence of other alleles, will result in a certain phenotype. Dominance is a phenomena in genetics when one version of a gene on one copy of a chromosome obscures or overrides another version of the same gene on the other copy of the chromosome.
Completely dominant alleles will always be expressed in the phenotypic of the cell. The dominant allele is therefore always expressed, but because penetrance might vary, it is sometimes not as clearly represented in the phenotypic of the cell as you would anticipate from a dominant allele.
Thus, the statement is accurate about dominant alleles is they are expressed whenever present. Hence option a is correct.

Fur color in animals is frequently controlled by more than one gene. However, brown fur in rabbits is dominant over white fur. A white female gives birth to all white rabbits, even though the father had brown fur. Show how this is possible.
Answers
Answer:
Please find how this is possible in the explanation below
Explanation:
This question is regarding a gene in rabbit coding for fur color. Brown fur (B) in rabbits is dominant over white fur (b). However, according to the question, a white female gives birth to all white rabbits, even though the father had brown fur. This is possible because the father is heterozygous for the brown fur i.e Bb.
Hence, in a cross between a heterozygous father (Bb) and a white mother (bb), the following gametes will be produced by the following parent:
Bb - B and b
bb - b and b
Using these gametes in a punnet square (see attached image), the probability of 1/2 of the offsprings will possess white fur (bb). Based on this result, the white female is able to give birth to all white rabbits because the male rabbit contributed the white allele (b).

The hypothalamus controls the body temperature and appetite. It releases different hormones to control that. The pineal gland secretes melatonin, which regulates the circadian rhythm of animals. The limbic system regulates different emotions such as happiness, anger, etc.
The hindbrain has a cerebellum. This regulates voluntary muscle movements like walking, etc. The medulla oblongata regulates involuntary activities such as heart rate, respiration, etc.
