As mentioned in the question that teeth discoloration is a X -linked dominant trait so a woman who has discolored teeth can have both the genotypes XAXA or XAXa. A dominant trait shows its effect even when only one of the copy of gene is mutated.
Add Answer to:
One type of teeth discoloration is a X-linked dominant trait. If a woman has discolored teeth,...

3. A trait determined by an X-linked dominant allele shows 100 percent penetrance and is expressed in 9 percent of the females in a population. Assuming that the population Is in Hardy-Weinberg equilibrium, what proportion of the males in this population express the trait? Show your work. (4 pts) *4.

1. In the P generation, whena homozygous dominant trait is crossed with a homozygous recessive trait, all the Figeneration will show the dominant trait. What will be the genotype and phenotype ratio in the F2 generation when the Fi generation is crossed? 2 In humans, brown eyes (B) are dominant over blue (b). A brown-eyed man marries a blue-eyed woman and they have three children; two of the children have brown eyes and one has blue eyes. Draw the Punnett...
