The types of gametes will be produced by a species of genotype TtRr are
A.
TR, Tr, tR, tr
AnswerB.
tR, Tr
C.
TR, tr
D.
TR, tR
Answer: Option A
Solution
Answer: Option A
Solution:
The types of gametes will be produced by a species of genotype TtRr are TR, Tr, tR, tr.All the offspring will be hybrid (heterozygous) tall, red flowering (TtRr). Since the genes for height are on a different pair of chromosomes from the genes for flower colour, the genes assort independently. This allows for four different types of "gametes" to form: TR, Tr, tR and tr.
