How many different types of genotypically distinct gametes c
How many different types of genotypically distinct gametes can an individual with the following genotype form? Aa; BB; cc; Dd; Ee; Ff 4 256 64 16 12
Solution
16 different types of genetically distinct gametes an individual produces with the following genotype AaBBccDdEeFf
Number of different kinds of gametes=2n
Here n is the number of heterozygous alleles
The number of heterozygous alleles in AaBBccDdEeFf is Aa, Dd, Ee and Ff, so altogether 4 heterozygous alleles are there.
Number of different kinds of gametes=2n=24=16 gametes
For example, AA produces only 1 kind of gamete
aa produces only 1 kind of gamete=a
But Aa produces two kinds of gametes= A or a in equal proportions.
AaBBccDdEeFf
2 x 1 x1 x2x2x2=16
Like this you can calculate the combination of gametes for any given combination of alleles
