Question

when dealing with a monohybrid cross, ______ gene(s) are being observed.
when dealing with a dihybrid cross, ______ gene(s) are being observed.
a 1, 2
b 2, 1
c 1, 1
d 2, 2

Explanation:

• A monohybrid cross involves the study of the inheritance of a single gene. For example, when looking at the inheritance of flower color (where there is one gene with different alleles controlling the color).
• A dihybrid cross involves the study of the inheritance of two different genes simultaneously. For instance, looking at both seed color and seed shape genes in a plant cross.

Answer:

A. 1, 2
