why do XY males have biallelic expression of some sex-linked genes?
Homework Answers
This is due to the presence of both X and Y chromosomes and this is explained in following figure below:

Name Sex-linked traits are genetic char segments of DNA found on chromosomes that Sex-Linked Traits Senetic characteristics determined by genes located on sex chromosomes. Genies are and on chromosomes that carry information for protein production and that are sponsible for the inheritance of specific traits Genes exist in alternative forms called alleics. or a trail is inherited from each parent Like traits originating from genes on autosomes (non-se chromosomes), sex-linked to omosomes), sex-linked traits are passed from parents to offspring...

Which of the following explains why most sex-linked characteristics are X-linked instead of Y-linked? Group of answer choices A All the genes on the Y chromosome are recessive B The X chromosome has more genes than the Y chromosome C Genes on the Y chromosome contain more mutations than on the X chromosome D There are no YY genotypes

39 of 45 Why are sex-linked conditions more common in men than in women? Women simply do not develop the disease regardless of their genetic composition. Men need to inherit only one copy of the recessive allele for the condition to be fully expressed. The sex chromosomes are more active in men than in women. Men acquire two copies of the defective gene during fertilization. Men have more linked genes.

Women have sex chromosomes of XX, and men have sex chromosomes of XY. Which of the women's grandparents could not be the source of any of the genes on either of her X- chromosomes? O Mother's Mother. O Mother's Mother and Mother's Father. Father's Father O Father's Mother. O Mother's Father.

*why do sex-linked traits (X- linked traits) such as red-green colorblindness (which is recessive) display a different pattern of genetic inheritance from autosomal recessive traits? and does it make a difference whether the sex-linked trait is dominant rather than recessive? how? *what are the chances a boy will be colorblind if his mothers father was color blind?

In moths, males are homogametic. Spotted wings (s) are recessive to the wild-type and sex linked. A wild-type male is mated to a spotted female, and all the F1 are wild-type. If these F1 males are mated to F1 females, what will be the ratio of wild-type to spotted females in the F2?
Experimental prediction: Comparing autosomal and sex-linked inheritance
You now know thatinheritance of eye color in fruit flies is sex-linked: The gene encoding eye color is located on the X chromosome, and there is no corresponding gene on the Ychromosome.How would the inheritance pattern differ if the gene for eye color were instead located on an autosome (a non-sex chromosome)? Recall that for autosomes, bothchromosomes of a homologous pair carry the same genes in the same locations.Suppose that a geneticist crossed a large number of white-eyed females with...

SEX-LINKAGE Red-Green color-blindness is sex-linked X-linked recessive trait. A normal sighted woman whose father is color- blind marries a color-blind man. they have 20 children. Of those 20, 6 are normal sighted females, 5 are color-blind females, 4 are normal sighted males and 5 are color-blind males. 7. What are the genotypes of the parents and all the children? 8. Theoretically, what would be the genotypic and phenotypic ratios of the offspring?
