Question

How many different kinds of gametes are produced by the F1 offspring from a cross between pure strain of plants with yellow peas and a pure strain of plants with green peas? 1) 12) 23) 34)8explain in detail​

Answer 1

Answer:

f1 offspring produces two types of gametes since it is heterozygous.

It produces gamete Y and y for gene yellow and green respectively

Answer 2

Two types of gametes are produced  by the F1 offspring from a cross between pure strain of plants with yellow peas and a pure strain of plants with green peas.(option - 2)

• Number of gametes can be calculated by the formula - 2ⁿ, n = number of heterozygous individuals.
• let the Dominant allele and recessive allele for color of the peas be Y and y respectively.
• YY - Yellow peas strain
• yy - green peas strain
• yy × YY(crossing) - Yy (all offsprings)
• If F1 offspring is heterozygous, therefore one individual means 1 heterozygous, will produce 2 gametes.⇒ 2ⁿ = 2¹ = 2 types of gametes. → Y and y.
