Consider the cross of a homozygous white & horned male with a homozygous black & hornless female. What genotypes and phenotypes are expected in the F1? What genotypes and phenotypes are expected in the F2? In what ratios? Zappy is a horned white male. It was bred to the following four females, and the results are presented here:
In the fictitious monster Lochnessius coolnameii, coat color is under the control of an autosomal gene, with white coat (W) dominant over black coat (w). The monster’s ability to produce horns is a sex-influenced trait, that is dominant in males but recessive in females. Let Horned = H, and hornless = h.
- Consider the cross of a homozygous white & horned male with a homozygous black & hornless female. What genotypes and
phenotypes are expected in the F1? - What genotypes and phenotypes are expected in the F2? In what ratios?
- Zappy is a horned white male. It was bred to the following four females, and the results are presented here:
Mother Offspring
Alcremie: hornless, black 1 horned white female
Blissey: hornless, white 1 hornless black female
Chansey: horned, black 1 horned, white female
Delcattie: hornless, white 1 hornless, black male + 1 Horned white female
Deduce the genotypes of the five parents, to the extent that is possible.
