Which of the following phenomena is a consequence of independent assortment? a. the phenotypic ratio among phenotypes produced from an f1 x f1 dihybrid cross is 9: 3: 3: 1. b. for any gene displaying complete dominance, heterozygous individuals exhibit the dominant phenotype. c. pure breeding plants, when mated with each other, produce completely homozygous offspring. d. smooth seed trait is dominant to wrinkled seed trait in peas.

Option A, The phenotypic ratio among phenotypes produced from an F1 X F1 dihybrid cross is 9:3:3:1.

Explanation:

Two characteristics which are associated with two different genes are expressed independently without interfering with the expression of one another as per the law of independent assortment

In other words

The two different alleles received from two different genes in a  gamete do not influence the expression of each other.

In option A, the cross is between dihybrid species where two allele of two different genes are expressed freely

For example

shape of seed of peas (S) and color of the seed of peas(C) are two different characteristics which are expressed independently in a dihybrid cross

Hence, option A is correct

d bonding propertys

explanation:

carbon can form so many different compounds not just with oxygen
