Directions: Complete a Punnett square for the following genetics problems and provide genotypic and phenotypic ratios of offspring.

In rabbits, short hair (S) is dominant over long hair (s). What genotype and phenotype ratios are expected from a cross between two heterozygous shorthaired rabbits?

In sheep, white wool (W) is dominant over black wool (w). What genotype and phenotype ratios are expected from a cross between a heterozygous sheep with white wool and sheep with black wool?

In some plants, green pod color (G) is dominant to yellow pod color (g). If an individual that was heterozygous for green pods were crossed with one that was homozygous for green pods, identify the genotype and phenotype ratios of the offspring.

In some plants, having brown seeds (B) is dominant to having white seeds (b). What are the genotype and phenotype ratios that would be expected from a cross between an individual that is homozygous for brown seeds and one that has white seeds?

Thank you!! Will give Brainliest if possible!

Answer:

Sorry I couldn't draw the punnett squares. Also I'm not sure if you need to reduce the ratios or change them into percents but hopefully this helps

1.        S           s

    S   SS        Ss

    s    Ss         ss

Genotypic ratio- 1 SS: 2 Ss: 1 ss

Phenotypic ratio- 3 short haired: 1 long haired

2.         W          w

     w    Ww       ww

     w     Ww       ww

Genotypic ratio- 2 Ww: 2 ww

Phenotypic ratio- 2 white wool: 2 black wool

3.          G           g

     G    GG        Gg

     G    GG         Gg

Genotypic ratio- 2 GG: 2 Gg

Phenotypic ratio- 4 green pods: 0 yellow pods

4.          B             B

      b    Bb           Bb

      b    Bb           Bb

Genotypic ratio- 4 Bb: 0 bb: 0 BB

Phenotypic ratio- 4 brown seeds: 0 white seeds
