2 parents talk to hereditary guidance counselor. They did not recognize why all of their sons are colorblind (an X-linked trait) although none of their daughters are colorblind. Both of parents seem normal. How would you describe this to parents?

HELP WITH GENETICS PLEASE!!!***Sex Linkage Questions In humans, colorblindness is a sex-linked trait. Jordan and Jill are a married couple with two sons, Jordan Jr. and James. James is colorblind, but none of James’ grandparents are colorblind and neither is Jordan Jr. Jordan and Jill have a third child, a daughter name Jess. Jess is colorblind just like her brother James. Given this information, answer the following questions. 1.) What chromosome is the gene for colorblindness located on? Explain why...

the two cream colored guinea pigs produced, in one case, 22 yellow. 47cream, and 19 white. What type of inheritance is this? II. Sex-linked Characteristics 12. In man, colorblindness, an inability to distinguish between red and green, is inherited as a sex-linked character on the X chromosome. It is recessive. If a colorblind man marries a homozygous normal woman what chance is there for the children of being colorblind? If a normal man marries a colorblind woman. where will colorblindness...

For each of these problems, be sure to justify your answer(s) by including an allele key, parental cross (genotypes), phenotypes, and the resulting Punnett square representing all possible mating of eggs and sperm. 1. Tom and his wife Julie are both carriers for cystic fibrosis, an autosomal recessive disease. What is the chance that their children will have cystic fibrosis and carriers? 2. In cattle, a dominant “Dexter” gene, combined with its recessive allele, results in abnormally short legs, while...

Innn As you already know, color-blindness is an X-linked recessive trait. The frequency of males afflicted by the trait is 8% in the general population. Which of the following statements accurately describes the approximately 5,000 students (3,000 females and 2,000 males) that go to Fisher? [Again, assuming that Fisher is representative of the general population.] 1 400 males and 32 females are likely colorblind. (2) 13...

17) Why are dominant lethal alleles difficult to pass on? What are three circumstances in which dominant lethal alleles can be passed on to future generations? how do dominant lethals usually arise in a population if it is so difficult to pass them on? 18) What does it mean by male mammals being “hemizygous” for sex chromosomes? 19) Select the true statements about sex chromosomes and sex-linked genes. Circle all that apply. The Y chromosome only contains genes for “maleness”. In mammals, the father has no...
