Question

In mangoes, genotype aabbcc produces 10gm mangoes and AABBCC produces 180gm mangoes. What is the contribution of each polygene in the production of the mangoes?

• A. 12.50gm
• B. 25.62gm
• C. 28.33gm
• D. 30.35gm

Answer 1

The correct option is C 28.33gm

This is a case of polygene at work.

• When none of the alleles contributing the weight of the mangoes are 10gm.
• When each and every allele is contributing the weight of mangoes is 180gm.

So, individual weight contributed by each allele=(180-10)/ 6
28.33gm.
