Question

What was shown by a dihybrid cross during Mendel's experiments?

If an organism inherits a recessive allele for one gene, all of the organism's traits will be
recessive.
O The inheritance of one trait does not affect the chance of inheriting another.
O
If an organism has a dominant allele for one gene, all of the organism's traits will be
dominant.
O The genetic system of plants is fundamentally different from that of animals.

Answer 1

Mendel's dihybrid cross experiments showed that the inheritance of one trait does not affect the chance of inheriting another. The law of independent assortment states that traits segregate independently during inheritance. The expression of one trait is not influenced by the expression of another trait.

Step-by-step explanation:

Mendel's dihybrid cross experiments showed that the inheritance of one trait does not affect the chance of inheriting another. In a dihybrid cross, Mendel crossed pea plants that differed in two traits, such as pea color and pea shape.

He found that the two characteristics, pea color and pea shape, segregated independently, meaning that the expression of one trait was not influenced by the expression of the other trait. This is known as the law of independent assortment, which is Mendel's second law of inheritance.
