Question

How many phenotypes do you get if a plant with the genotype A/a ; B/b ; C/C ; D/d gets self-fertilized?

Answer 1

Given,

genotype of plant which gets self fertilized is Aa Bb CC Dd

number of heterozygous gene pairs in the plant ( n ) = 3

therefore,

total number of phenotypes produced if the plant gets self fertilized = 2ⁿ ( n is the number of heterozygous gene pairs )

   = 2³ ( here, n = 3 )

   = 8 ( Eight )
