PLEASE HELP ME WITH THIS!! I'M STUCK!! PLEASE HELP ME WITH THIS!! I'M STUCK!!

Imagine that a new species is identified and the transmission of a trait for a horn is being studied. The presence of a horn is dominant and represented as H. The lack of a horn is recessive and represented as h. What genotype and phenotype probabilities would exist for a cross between a horned organism (HH) and a horned organism (Hh)?

Answer 1

Explanation:

When you make the cross. You get

HH HH Hh Hh.

So the genotypic ratio - 2:2 which is also 1:1.

The phenotypic ratio - 4. Since Hh and HH are horned organisms. So they only differ in their genotypic make up.
