What is the law of independent association?

Answer 1

Examples of Law of Independent Assortment
The law of independent assortment applies well to most plants and animals, but only to those genes which occur on non-homologous autosomal chromosomes. Here, following dihybrid crosses of guinea pigs and Drosophila can be considered as the examples for law of independent assortment in animals.

1. When a black short haired guinea pig (BB SS, the black colour and short hairs dominate over brown colour and longhairs respectively) and a brown, long-haired- guinea pig (bb ss) are mated, the BB SS individuals produce gametes all of which are BS. The bb ss guinea pigs produce only bs gametes. Each gamete contains one and only one of each kind of gene. The union of BS gametes and bs gametes yields F1 heterozygous, black, short haired individuals with the genotype of Bb Ss.

However, when two of the F1 individuals are mated each produces four kinds of gametes in equal numbers-BS, Bs, bS, bs. These gametes unite to produce 16 combinations in F1 in the phenotypic ratio of 9 black, short haired: 3 black, long haired: 3 brown, short haired: 1 brown, long haired or 9 : 3 : 3 : I. The results of this cross have been represented by following diagram.

F2 Eggs Sperms 3-Black, Short Black, Short Black, Short Black, Short Black, Short Black, Short 3-Black, Long Black, Long Black, Long Black, Long Black, Long Black, Long 3-Brown, Short Brown, Short Brown, Short Brown, Short Brown, Short Brown, Short 1-Brown, Long Brown, Long Brown, Long Brown, Long Brown, Long Brown, Long
The results of this cross clearly show that the segregation of the B-b genes is independent of the segregation of the S-s genes.

Answer 2

The factors for each trait are separated independently when sex cells form.

Answer 3

The law of independent assortment states that pairs of allele separate independently during the formation of gametes. Mendel made this law after performing dihybrid crosses.

Answer 4

The chromosomes and genes are indePendently assorted

Answer 5

Law of independent assortment is allele pairs separate independently during the formation of gametes. This is taught in Biology.
