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)?

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.

answer

crater lake was formed when mount mazama produced a large eruption and collapsed to form a caldera, which then filled with water forming a lake.
