Reference no: EM1383339

A) In Drosophila (fruit flies) ebony body color and being eyeless are both autosomal recessive traits. An ebony fly is mated with an eyeless fly and the F₁ are all wild type.

The F₂ are:

590 wild type

185 eyeless

200 ebony

72 eyeless and ebony

Test the hypothesis that this was a dihybrid cross (ratios) using the Chi Square test.

B) A corn plant with purple, full kernels is crossed with a plant having purple, full kernels. The following progeny are obtained:

Purple, full 100

Purple, shrunken 36

Yellow, full 30

Yellow, shrunken 8

Determine the genotypes of the parents and progeny.

Test your hypothesis with a Chi square test until it is accepted.
