You have been studying two Hippogriff traits as a senior graduation project at Hogwarts (because you are magical), beak size (big beaks, B, are dominant to small beaks, b) and feather color (brown feathers, F, are dominant to white feathers, f). You mate two brown, big-beaked Hippogriffs and obtain the following results: 15 of the baby Griffs are brown and big-beaked; 4 of the baby Griffs are white are big-beaked; and 1 of the baby Griffs is white and small-beaked. What are the genotypes of the parent Hippogriffs

BbFf is the genotype of parent Hippogriffs

Explanation:

Given -

Big beaks, B, are dominant to small beaks, b.

Brown feathers, F, are dominant to white feathers, f.

Two brown, big-beaked Hippogriffs are mated to produce 15 brown and big-beaked; 4  white and big-beaked; and 1  white and small-beaked offspring

The genotype of parents is BbFf

1. is geographic distribution

2 is increasing complexity

3 is transitional forms

all these collisions do one thing, and that thing is explained in the last option. when dusst, rocks and ice collide, they harden and form giant layers of rocks or hard ice.

d)   to harden materials to form different parts of earth’s layers
