Question

-------- new combinations of traits had appeared in the dihybrid cross.​

Answer 1

This established the law of independent assortment, according to two which when two homozygous parents differing in a pair of traits are crossed, the alleles of the two traits assort (distribute) independently of the parental combinations.

Answer 2

Answer:

According to Mendel's law of independent assortment, during the inheritance of two or more characters, the assortment of individual traits takes place independently during gamete formation.

Thus, each allele of a pair segregates independently and each gamete formed contains one allele of that trait.

When F

1

generation was selfed, a recessive character reappeared in F

2

generation.

This shows that the recessive gene was present and separated out independently during the production of gametes and the progenies exhibited a recombination of parental traits.
