    but how 12.5%equals to 10%?

    yes it is not equal to 10, but 10% is nearby value of 12.5 so answer is 10%. Out pf 8 gamets only one will be AbC.

    sorry but not satisfied with your answer.

    eduncle-logo-app

    To find the no.of gametes use the formula 2^n, where n is no of heterozygous alleles. here there are 3 heterozygous alleles. so there will be total 8 gametes possible. Out of 8 gamete only one will be AbC i.e. 1/8. Which come 12.5. the nearest value is 10%. So answer will be 10%.
