Answer:
1/2 wWBb , White wool and brown eyes.
1/2 wWbb , White wool and blue eyes.
Explanation:
White wool (W) is dominant over black wool (w).
Brown eyes (B) is dominant over blue eyes (b).
A sheep with black wool (ww) and brown eyes (Bb) is crossed with a sheep with white wool (WW) and blue eyes (bb).
<h3>wwBb x WWbb</h3>
If there is independent assortment between genes, the genotypes of the first parent's gametes will be wB and wb. The gametes of the second parent can only be Wb.
<u>The resulting offspring will be:</u>
- 1/2 wWBb , White wool and brown eyes.
- 1/2 wWbb , White wool and blue eyes.

Answer:
Genotype ratio: 1, 1:1, 1:2:1
Phenotype ratio: 1, 3:1
Explanation:
Single gene pair cross is also known as monohybrid cross. This means that only one gene usually with two alleles is observed and it express one trait.
For example, if we name the gene for a certain trait with A, the possible genotypes are AA (dominant homozygous), aa (recessive homozygous) and Aa (heterozygous). Possible crosses are:
P: AA x AA
F1 : all of them are AA
The same is with aa x aa (all of the offspring are with aa genotype)
P: AA x Aa
F1: AA Aa AA Aa (genotype ratio 1:1) (phenotype ratio 3:1)
The same genotype ratio is in aa x Aa (offspring will have aa Aa aa Aa-(genotype ratio 1:1) (phenotype ratio 1:1)
P: Aa x Aa
F1: AA Aa Aa aa (genotype ratio 1:2:1) (phenotype ratio 3:1)
P: AA x aa
F1: Aa Aa Aa Aa (1)
