The law of independent assortment . a. states that the alleles at different loci segregate independently from one another during a dihybrid cross can account for a 9:3:3:1 ratio seen in the F2 generation applies only to genes that are present on different chromosomes (or behave as if they were) b. The first and second answers are correct. c. The first, second, and third answers are correct.

B) The first and second answers are correct.

Explanation:

The law of Independent assortment is one of the four laws of Mendel which states that alleles located on the chromosomes segregate or assort independently of each other.

This means that whether they are present close to each other or they are present at a distance they can be passed on in the generation together but they will show their effect on the phenotype independent of each other.

The law was concluded form the result of the dihybrid cross which showed that although the two genes were controlling the trait each allele will show its effect independent of each other or like a monohybrid result.

Thus, Option-B is the correct answer.

the backbone of the dna and rna compound is sugar phosphate.
