Question

please help FAST how do you fill in a Assignment: Using Punnett Squares Exploration

Answer 1

You should draw these simple Punnett Squares as it's easy to see the answers:

1. Crossing RR x Rr results in all (100%) red cow offspring. 50% will be RR (homozygous dominant), 50% will be Rr (heterozygous).

2. Crossing Rr x Rr results in 3 red offspring (75%) and 1 white (25%). Genotypes though will be 25% RR, 50% Rr, and 25% rr.

3. Crossing rr x rr will result in 100% white offspring. All offspring will be rr.

Answer 2

Answer:

Explanation:

✔✔Therefore:Crossing results in 50% (dominant homozygote) and 50% (dominant heterozygote).

b)

✔✔Therefore:Crossing results in 25% (dominant homozygote), 50% (dominant heterozygote) and 25% (homozygous recessive).

c)

✔✔Therefore:Crossing results in 100% (homozygous recessive).
