I

I. Work the P1, F1 and both F2 monohybrid crosses for each of the other pea plant traits

1. Seed color - Yellow (Y) or Green (y) 
2. Plant height - Tall (T) or Short (t)
3. Seed coat color - Gray (G) or White (g)

II. Do a dihybrid cross for the following: 

1. Cross a pea plant that is heterozygous for purple flowers and homozygous dominant for yellow seeds with a plant that is heterozygous for purple flowers and homozygous recessive for green seeds.
2. Cross a plant that is heterozygous for round seeds and homozygous recessive for white flowers with a plant that is homozygous recessive for wrinkled seeds and heterozygous for purple flowers.
3. Cross a plant that is heterozygous tall and homozygous for green seeds with a plant that is short and is also homozygous for green seeds. 

Symbols (for pea plant traits):

T: Tall t: short

R: Round seeds r: wrinkled seeds

Y: Yellow seeds y: green seeds

P: Purple flower p: white flower
