what are the sex/phenotype of offspring from a cross of true-breeding white-eyed male and red-eyed female drosophila? a) red eyed males, white eyed females b) white eyed males, red eyed females c) red eyed females, 1/2 males red eyed 1/2 males white eyed d) red eyed males, red eyed females
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....

What are the genotypes of each parent? b. What fraction of the children will have red eyes? c. What fraction of the children will have white eyes? d. What fraction of the female children will carry the white eyed trait? 3. In humans, hemophilia is a sex-linked recessive...
what are the sex/phenotype of offspring from a cross of true-breeding white-eyed male and red-eyed female drosophila?
A (w-/ w-) white-eyed Drosophila female is crossed with a red-eyed male. Assuming the trait for eye color is sex-linked, what are the possible phenotypes of the progeny? All red-eyed individuals Red- and white-eyed females and males Only red-eyed females and white-eyed males Both red- and white-eyed males and only white-eyed females None of these
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...
Hemophilia is a sex-linked recessive trait. If a hemophiliac male marries a carrier female, what percent of their daughters will have hemophilia? The gene for yellow body color in Drosophila is recessive and sex-linked. Its dominant allele b+ produces wild-type body color while the recessive allele, b- produces yellow body color in homozygous individuals. List the phenotypes and genotypes of the progeny from the following matings: a. yellow female x wild-type male b. wild-type (carrier) female x wild-type male c....
In TH Morgan’s experiment, of crossing a pure-bred red-eyed female with a white-eyed male: a. F1 had all red-eyed males and females b. F1 had all white-eyed males, and red-eyed females c. F1 had all white-eyed females, and red-eyed males d. F1 had all white-eyed males and females e. None of the above
