Question

Wolves will either have gray coats (G) or black coats (g), brown eyes (B) or blue eyes (b). If a male wolf with a black coat and blues eyes breeds with a female wolf heterozygous for coat and eye color??

What is the chance their offspring will have the following genotypes?
Write them in ratio form out of 4.
Im not sure if i write 4 punnet square

Answer 1

See below.

Explanation:

Understand what you're working with. You have a dominant-recessive cross for two traits.

First, start with the trait that you're interested in.

1. Trait: eye colour, coat colour

Second, write out the key for possible combinations of traits you have.

1. Key

Genotype Phenotype
Coat colour
GG Grey
Gg Grey
gg Black

Eye colour
BB Brown
Bb Brown
bb Blue

Then, write down the genotypes of the parents.

1. Mom: Gg, Bb; Dad: gg, bb

Your possible gametes are:

From mom: GB, Gb, gB, gb
From dad: gb

Then, do your Punnett square

1. 

Now that you got all the possible kid genotypes, write them out

1. Genotypes: Gg,Bb; Gg, bb; gg, Bb; gg,bb

2. Genotypic ratio: 1:1:1:1

3. Phenotypes: grey coat, brown eyes, grey coat blue eyes, black coat brown eyes, black coat blue eyes.

4. Phenotypic ratio: 1:1:1:1

And you're done!
