I have some science biology problems i am really stuck on. I'm a freshman by the way and yes i do get A's &Bs

Question

1. TT x tt Parent genotypes: ______________
Offspring genotypers _____________
Phenotyc Ratio _________________



2. Three-Fourths (3/4) of the plants produced bya cross between two unknown pea plants have axial flowers and 1/4 have terminal flowers. What are the genotypes of the parent plants?

Flower Position
Axial (A)
Termianal (a) Parent Genotypes___________




3. What cross would result in 1/2 of the offspring having green pods and 1/2 of the offspring having yellow pods?

Pod Color
Green (G)
Yellow (g) Cross:__________________

The teacher who taught us this didn't take her time and i don't get how to do this.

Answer 1

1. TT x tt Parent genotypes: TTxtt
Offspring genotypers:Tt=4/4
Phenotyc Ratio:t assuming its talls or short Tall:4/4100%


2. Three-Fourths (3/4) of the plants produced bya cross between two unknown pea plants have axial flowers and 1/4 have terminal flowers. What are the genotypes of the parent plants?

Flower Position
Axial (A)
Termianal (a) Parent Genotypes: AaxAa




3. What cross would result in 1/2 of the offspring having green pods and 1/2 of the offspring having yellow pods?

Pod Color
Green (G)
Yellow (g) Cross:Ggxgg

Answer 2

1. TT Parent genotype: homozygous dominant
tt Parent genotype: homozygous recessive
offspring genotypes: 100% heterozygous

2. Both parents were heterozygous. (Aa and Aa)

3. One heterozygous (Gg) parent nad one homozygous recessive (gg) parent.

Answer 3

I hope this will help, just click on it.
