In carrots, the yellow color of root crops dominates over red. The red root plant was crossed with a homozygous yellow root plant. In F1 received 315 plants. In F2- 1180. 1) How many different types of gametes are there in F1? 2) How many plants with recessive traits are there in F2? 3) How many heterozygous plants are there in F2? 4) How many dominant homozygous plants are there in F2? 5) How many plants in F2 are red?

R: aa * AA

gametes: a; A

F1: Aa (yellow)

P2: Aa * Aa

gametes: A a; A a

F2: AA Aa Aa aa

1) In F1 there are 2 types of gametes.

2) 25% of first generation hybrids – 1180 * 0.25 = 295

3) 50% – 590 hybrids are heterozygous

4) 25% – 295 hybrids dominant homozygotes

5) 25% – 295 hybrids are red
