The following Drosophila crosses were performed Cross 1 Parents: white-eyed straight winged male x red-eyed; curly winged female Progeny: all red-eyed flies, half of which are curly winged Cross 2 (reciprocal cross) Parents: red-eyed curly winged male x white-eyed straight winged female Progeny: white-eyed males and red-eyed females, half of each have curly wings. Test crosses with the curly winged progeny from cross 1 and 2 to homozygous straight winged flies resulted in all half curly and half straight winged...
In cats with tortoiseshell coat color, the fur is white with patchy black and orange spots. In cats, the tortoiseshell gene is on the X chromosome, and the tortoiseshell phenotype requires the presence of 2 different alleles at this locus: one for orange fur (o) and one for black fur (b). What phenomenon best explains why female cats can inherit tortoiseshell coat color? In females, the alleles for coat color are pleiotropic, resulting in patches of orange and black coat...
In cats fur colour can be black, orange or tortoise (patched orange and black). A mating between two cats produces the kittens indicated below. P: tortoise female X orange male F1: orange females tortoise females black males orange males What are the genotypes of the parents and F1 progeny, if fur colour is controlled by X-linked alleles?
16. So far we have been dealing with alleles found on autosomal chromosomes. These chromosomes contain all the genetic information that is not gender related. As a human, you have 44 autosomal chromosomes (22 pairs → 11 chromosomes from your Mom and 11 chromosomes from your Dad). You also contain a pair of sex chromosomes. These chromosomes contain all the genetic information related to your gender. If you are female, you received an X chromosome from your Mom and an...
(Problem 66a) Male house cats are either black or orange; females are black, orange, or calico. If these coat-color phenotypes are governed by a sex-linked gene, how can these observations be explained? A.The gene is on the X chromosome and three alleles must be involved. B.Calico males die before birth C.In males, orange is always dominant over calico. D. The gene is on the X chromosome and heterozygous females display the calico phenotype. . E.Calico males are sterile. (Problem 66...

all of them please Question 10 (1 point) In Drosophila, the mutant black (b) has a black body and the wild-type (b+) has a gray body; the mutant vestigial (v) has wings that are short and crumpled compared the long wild-type wings (V+). These genes are linked and are located on the X- chromosome. A cross between a female fly and a black, vestigial winged male fly produced the following progeny: gray (b+), normal (v+) 20 gray (b+), vestigial (v)...
5. Show the cross of a red eyed female (heterozygous) and a red eyed male What are the genotypes of the parents? How many of the offspring are white eyed, male white eyed, female red eyed, male red eyed, female 6. 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 theywon'tever be carriers) XHXH=female, non-hemophilic X H X h female, carrier Xh Xh-...
how would you test if the genes for body color (B dominant over b) and wing shape (V dominant over v) were linked (close to each other on the same chromosome)? In tortoiseshell cats, a gene on X chromosome determines fur color. Explain why female but not male cats have mosaic fur, containing patches of orange and black color.
