Club foot is one of the most common congenital skeletal abnormalities, with a world-wide incidence of about 1 in 1000 births. Both genetic and nongenetic factors are thought to be responsible for club foot. C.A. Gurnett et al. identified a family in which club foot was inherited as an autosomal dominant trait with reduced penetrance. They discovered a mutation in the PITXI gene that caused club foot in this family. Through DNA testing, they determined that 11 people in the family carried the PITXI mutation, but only 8 of these people had club foot. What is the penetrance of the PITXI mutation in this family

Answers

Answer 1

Answer:

0.727

Explanation:

Penetrance can be defined as a measure of the association between a genotype and phenotype. In medical genetics, the penetrance of a mutation leading to the disease state is the proportion of individuals carrying the mutation and showing disease symptoms associated with such mutation. For example, if a mutation leading to the disease state has a 90% of penetrance, it is expected that 9 of each 10 individuals carrying the mutation will develop the disease, while the remaining 10% will not develop the disease. In this case, 8 of each 11 individuals carrying the PITXI mutation show symptoms compatible with the disease, and therefore the penetrance is 8/11 = 0.727 (73%).

Answers

A serving size is the amount of food that you should eat. It’s determined by how nutritional a food is. If it is healthy and has less calories, it’s serving size would be larger than if it was unhealthy will more calories. Serving sizes are not the same for every food because each food has its own nutritional values and calories.

Answers

Answer:biological parents provide a rearing environment for a child

Explanation:

According to Sandra Scarr's description on the correlation that exist between heredity and the environment, passive genotype-environment correlations occur due to the fact that certain genes evoke environmental support.

It should be noted that passive genotype-environment correlation takes place due to the fact that there's passive inheritance on the genes of the children and the environment which are provided by their parents.

An example of such characteristics is when the child is athletically inclined as it's possible for the family to be athletes.

In conclusion, the correct option is D.

Answers

Answer:

A)

Colorful and vocal birds may be eaten by predators with greater frequency,

so this is a poor adaptation.

Explanation:

Colourful and vocal male birds may attract the most mates and pass on their genes. Therefore, option (B) is correct.

What is evolution?

Evolution is the process of gradual change in the characteristics of a population over time through the mechanisms of natural selection, genetic drift, and gene flow, resulting in the emergence of new species.

While it is true that colourful  and vocal birds may be more visible to predators and more likely to be eaten, the fact that they have evolved to develop these traits indicates that the benefits of attracting mates and passing on their genes outweigh the risks of predation. Male birds use their coloration and vocalizations to attract females and demonstrate their genetic fitness, and females select mates based on these traits. Therefore, over time, the male birds with the most attractive traits will be more successful at reproducing, leading to the evolution and persistence of these traits in the population.

D. Returning bred plants to their natural habitat

Answers

Answer:

b

Explanation:

they chose the best tomatoes to make even better ones

Breeding tomatoes to increase fruit size is an example of selective breeding. Therefore option A is correct.

Selective breeding, also known as artificial selection, involves the intentional breeding of plants or animals to promote desired traits. The process typically involves selecting individuals with specific characteristics and breeding them to pass on those traits to the next generation.

In the given options, breeding tomatoes to increase fruit size is an example of selective breeding. By carefully selecting tomato plants with larger fruits and allowing them to reproduce, breeders can gradually enhance the fruit size of future generations.

This process relies on natural genetic variation within the tomato population and human intervention to guide the breeding process toward the desired outcome.

P is parent gene, and then the offspring goes to the F1 and then F2, the dominant gene is what gene wins over a recessive. So the answer is c

The preferred generation of hybrid offspring is called the P generation and can often be used to determine the dominant gene.

What is P generation and dominant?

Dominant directs to the relationship between two versions of a gene. Then, Individuals receive two versions of each gene, which are called alleles, from each parent. When the alleles of a gene are different, So, one allele will be expressed This is a dominant gene.

When The P generation is the start of Mendel's work on inheritance, or receiving genetic qualities by transmission from parent to offspring. So, Basically that it refers to traits or genes that are passed from a parental generation to its offspring

When P is the parent gene, and also then the offspring goes to the F1 and also then F2, the dominant gene is what gene wins over a recessive. So the correct option is 'C'.

The CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats)-Cas (CRISPR-associated) technology is widely used in medicine and research. The CRISPR-Cas is a versatile RNA-programable genome editing system capable of introducing genetic modifications at target DNA sequences. This technology is based on the natural bacterial immune system that cleaves bacteriophages and plasmid DNA sequences. Moreover, Genetically Modified Organisms (GMO) have historically raised three major concerns on human health: 1-the allergenicity of GMO foods, 2-the ability that GMOs might have to insert genes through horizontal transfer and 3-outcrossing between GMOs and (genetically) unmodified crops, which are further consumed as non-GM foods.

Over 30 children younger than three years of age developed gastroenteritis after visiting a local water park.

No this is not an outbreak

Explanation:

No it cannot be classified as outbreak because an outbreak is when the number of affected individuals in an epidemic is much higher as compared to the estimated values. However, an epidemic is the one that affects the people around different countries of the globe.

This can be considered as endemic that is restricted to a certain set of people in a community
