Question

What are Monohybrid and Dihybrid cross?

Answer 1

Cross:

1. The cross is the consequence of the genetic material combining between two individuals, resulting in the development of offspring.
2. Both parents' genetic material is present in the offspring. The cross happens when two people who are compatible and closely connected meet.

Monohybrid cross:

1. To explore the inheritance of a single allelic pair, two pure line organisms are crossed.
2. There are two sorts of gametes in it.
3. There are four offspring produced.
4. The phenotypic and genotypic ratio is 3:1 and 1:2:1 respectively.
5. Example: A pea plant cross between tall and short plants.

Dihybrid cross:

1. To explore the inheritance of two pairs of alleles, two pure line organisms are crossed.
2. It contains four different types of gametes.
3. A total of sixteen children are produced.
4. The phenotypic ratio is 9:3:3:1, while the genotypic ratio is 1:2:1:2:4:2:1:2:1.
5. Crossing round and yellow pea seeds with wrinkled and green pea seeds is a good example.
