A hollandic gene in man determines the growth of long hairs in
the auricles. When a man with this trait marries a woman
normal:
a) What percentage of your male children are expected to have the
trait?
b) What proportion of the daughters will have the trait?
Homework Answers

Parents Hollandic Man XY X XX Normal women
Offspring XX All Daughter are normal : XY All males are hollandic.
A. 100% male children are expected to have the trait.
B. 0% daughters will have the trait.

In humans, hemophilia is a sex linked trait. Females can be normal, carriers, or have the disease. Males will either have the disease or not (but they won’t ever be carriers) X H X H = female, normal / X H Y = male, normal X H X h = female, carrier X h X h = female, hemophiliac / X h Y= male, hemophiliac Show the cross of a man who has hemophilia with a woman who is a carrier....

1. A woman with white skin has intermediate parents. If this woman marries a man with light skin, what is the darkest skin color possible for their children? The lightest? 2. A woman is color blind. What are the chances that her sons will be color-blind? If she married a man with normal vision, what are the chances that her daughters will be color blind?

3. Colour-blindness is a X-linked, recessive trait. If a normal-sighted woman, whose father was colour-blind, marries a colour-blind man, what is the probability that they will have a son who is colour-blind? (use the letter "B") 4. A man and woman, both of normal vision, have: 1) a colour-blind son (#1) who has a daughter of normal vision 2) a daughter (#1) of normal vision who has one colour-blind son and one normal vision son 3) another daughter (W2) of...

In humans, normal pigmentation is due to a dominant gene A. Albinism is due to a recessive allele a. A normal man marries an albino woman and their first child is albino. What are the genotypes of all three people? If they have more children what would their pigmentation be like?

A color-blind woman marries a man who is not color-blind and they have six children ( 3 boys and 3 girls) All of the sons and none of the daughters are color blind. a. What does this tell you about the color blind allele? b. Draw the pedigree of this family, using correct symbols and all of the genotypes you can determine with certainty. c. One of the daughters marries a man who can see color. State the phenotypic and...

Red-green color blindness is inherited as an X-linked recessive (Xc). If a color-blind man marries a woman who is heterozygous for normal vision, what would be the expected phenotypes of their children with reference to this character? In your answer, specify in your phenotype descriptions the gender of the children. (For example, don’t just say 75% of the children would be colorblind – you would instead say 100 % of the daughters would be colorblind and 50% of the sons...

Green-weakness partial color blindness, or deuteranomaly, is a sex-linked recessive trait. The green-weakness allele, g, is recessive to the allele for normal color vision, G. Another form of abnormal vision is total color blindness which is due to an autosomal gene, t, which is recessive to its counterpart allele, T, for normal vision. A man with a normal phenotype marries a woman with green-weakness partial color blindness. Both individuals are heterozygous for autosomal color blindness. What phenotypes and phenotypic frequencies...
