Question

If you have the two traits for a plant include T-tall, t-short, G-green seed and g-yellow seed. If you cross a homozygous tall, yellow seeds (Parent 1), with a herezogous for both traits (parent 2), match the following.
Hint: do the cross

i.Genotypes for tall, green seed

Answer 1

Answer:

1. Parent 1 is TTgg

2. Parent 2 is TtGg

3. The genotype ratio is 1:1:1:1

4. The phenotype ratio is 2:2

5. 50% has tall and yellow seeds

6. Genotype for tall and green seed is TTGg, TtGg

Explanation:

The parent 1 is homozygous tall, yellow seeds, therefore the genotype is TTgg, While parent 2 is herezogous for both traits, therefore the genotype is TtGg.

Crossing the two parents gives children with the following traits:

Parent 1 gamete: Tg                           Parent 2 gamete:     TG   Tg   tG   tg

TTGg, TTgg, TtGg, Ttgg

The cross gives: TTGg, TTgg, TtGg, Ttgg

Therefore, 2 is tall and green, 2 is tall and yellow

The phenotype ratio is 2:2

The genotype ratio is 1:1:1:1

1. Parent 1 is TTgg

2. Parent 2 is TtGg

3. The genotype ratio is 1:1:1:1

4. The phenotype ratio is 2:2

5. 50% has tall and yellow seeds

6. Genotype for tall and green seed is TTGg, TtGg
