In the genetics lab, you crossed your favorite corn (rr red) to an unknown type of corn. you counted kernel colors and found bot

goldenfox [79]

The unknown type of corn had to be yellow.

There were offspring that were red and yellow.

The red corn only has recessive alleles (r and r) so, the yellow alleles( R) didn't came from this type. They came from a yellow type corn.

And since the offspring were NOT all yellow (the dominant color) we know that the yellow corn was heterozygous for the color trait (Rr).

50% red (rr)
50% yellow (Rr)

Q:- Wing coloration in the magpie moth, a species

Fudgin [204]

Answer:

a) All males will have dark wings, all females will have light wings. See attachment

b) Males - 50:50 dark:light, females, 100% dark wings

Explanation:

The ZW sex determination system is different from the XY sex determination system. Females are ZW, whereas males are ZZ (in contrast to XY system where females have two of the same chromosome [XX] and males have two different ones [XY]).

a) The potential genotypes of the F1 are shown in attachment. This shows that all males will have dark wings (Ll) (all heterozygous) and all females will have light wings (l) (all will inherit l allele from father)

b) The potential genotypes of the F2 are shown in attachment. This shows that 50% of the males will have light wings (Ll), and 50% will have dark wings (ll). All of the females will have dark wings (L).
