Wild type flies have gray bodies and red eyes. A fly exhibiting the autosomal recessive traits ebony body (genotype ee) and brown eyes (genotype bb) is crossed with wild type to produce dihybrids (Ee Bb), and these are intercrossed. A fly showing both dominant phenotypes is selected at random from the F2 population and crossed with a ebony body, brown eye tester (ee bb). There are two progeny classes from that cross: gray bodies and red eyes, gray bodies and brown eyes. What was the genotype of F2 fly used for the final cross described? Ee Bb Ee BB EE Bb

Transcribed Image Text:Wild type flies have gray bodies and red eyes. A fly exhibiting the autosomal
recessive traits ebony body (genotype ee) and brown eyes (genotype bb) is
crossed with wild type to produce dihybrids (Ee Bb), and these are intercrossed.
A fly showing both dominant phenotypes is selected at random from the F2
population and crossed with a ebony body, brown eye tester (ee bb). There are
two progeny classes from that cross: gray bodies and red eyes, gray bodies and
brown eyes. What was the genotype of F2 fly used for the final cross described?

Transcribed Image Text:A man has ichthyosis, an X-linked recessive trait that causes him to have dry
scaly skin all over his body. His wife does not display the trait. This couples'
daughter has patches of dry scaly skin, but most of her skin is not dry and scaly.
Which of the following mostly likely explains the patchiness of ichthyosis in the
daughter?
Translocation
Non-disjunction
Haplo-insufficiency
X-inactivation
