Question

What is the maximum number of allele that monohybrid cross can consider?

(a) 1

(b) 2

(c) 4

(d) 8

The question was asked during a job interview.

My enquiry is from Monohybrid Cross in chapter Mendelian Genetics of Cytogenetics

Answer 1

The correct choice is (b) 2

To explain I would say: If a gene is heterozygous it will have two different alleles for the same gene, thus in case of monohybrid cross where only a single gene is considered maximum two alleles are under consideration. For dihybrid cross the number will be 4.
