What is the chance of producing a son with normal vision if the father is colorblind and the mother is homozygous normal explain?

For example, if a mother is a carrier for colorblindness (X+Xc), and a father has normal vision X+Y, then their sons have a 50% chance of colorblindness because they inherit their X chromosome from their mother and their Y chromosome from their father.

Is it possible to determine the genotype of an individual having a dominant phenotype quizlet?

is it possible to determine the genotype of an individual having dominant phenotype? how? yes, look at their family (parents, offspring, etc.) what are the chances of two parents who carry the gene for albinism (an autosomal recessive disorder) having a child with albinism?

Is it possible to determine the genotype of an individual having a dominant phenotype how?

There is no way to tell these genotypes apart visually, but there is a well-established experimental technique to determine the fly’s genetic makeup. Specifically, to detect the underlying genotype of an organism with a dominant phenotype, one must do a type of breeding analysis called a test cross.

What is the probability that their first female child will have CF?

There is a 1-in-4 chance (25% of the time) the child will receive a CF gene from each parent (two abnormal genes total) and will be born with CF disease. There is a 2-in-4 chance (50% of the time) the child will receive 1 CF gene from 1 parent and a non-CF normal gene from the other parent.

Is it always possible to determine the genotype of an individual who has a dominant phenotype Why or why not?

Bottom line is you can’t always figure out genotype from phenotype with a dominant trait because dominant traits can happen with two different genotypes.

What are the possible genotypes of the offspring and what percentage of the offspring is likely to show the dominant phenotype?

What are the possible genotypes of the offspring and what percentage of the offspring is likely to show the dominant phenotype? AA and Aa will result; 100% will have the dominant phenotype.

Can a baby have cystic fibrosis if only one parent is a carrier?

A child will be born with CF only if they inherit one CF gene from each parent. A person who has only one CF gene is called a CF carrier. They are healthy and don’t have the disease. But they are a carrier of the disease.

How common is it to carry the cystic fibrosis gene?

It is estimated that approximately 1 in 35 Americans is a carrier of the CFTR gene mutation, which means more than 10 million Americans are cystic fibrosis carriers.

Can a child have cystic fibrosis if only one parent is a carrier?

If only one of you is found to be a carrier, the chance that you will have a child with CF is very low, although not completely eliminated. If you are both carriers, each pregnancy will have a 1 in 4, or 25 percent chance of being affected with cystic fibrosis.

What is the percentage likelihood that the couple will have a child with cystic fibrosis?

CF carriers can pass their copy of the CFTR gene mutation to their children. Each time two CF carriers have a child together, the chances are: 25 percent (1 in 4) the child will have CF.
