Explanation:
A monohybrid cross involves the study of one trait at a time, while a dihybrid cross involves the study of two traits simultaneously.
A monohybrid cross is a genetic cross that involves the study of one trait at a time. It is focused on analyzing the inheritance of only one pair of alleles. In contrast, a dihybrid cross is a genetic cross that involves the study of two traits simultaneously. It is used to determine the patterns of inheritance for two different gene pairs.
For example, let's consider a monohybrid cross involving flower color in pea plants. If we cross a purebred yellow flowered pea plant (YY) with a purebred green flowered pea plant (yy), the resulting offspring will all have yellow flowers (Yy). In a dihybrid cross, we would consider two traits, such as flower color and seed shape. We could cross a purebred yellow, round-seeded plant (YYRR) with a purebred green, wrinkled-seeded plant (yyrr), resulting in offspring with yellow, round seeds (YyRr).
In summary, the main difference between a monohybrid cross and a dihybrid cross is that a monohybrid cross focuses on one pair of alleles for one trait, while a dihybrid cross focuses on two pairs of alleles for two different traits.
