Question

Independent assortment explains _______. View Available Hint(s) Independent assortment explains _______. why meiosis in a cell of genotype Aa yields A gametes and a gametes in roughly equal numbers why meiosis in a cell of genotype AaBb cannot yield Ab gametes why meiosis in a cell of genotype Aa yields A gametes and a gametes, but no Aa gametes why a collection of meiotic products that includes gametes of genotype Ab will also include gametes of genotype AB in roughly the same proportion

Answer 1

Independent assortment explains why gametes include different genotype combinations in equal proportions, occurring during meiosis with each pair of alleles segregating independently, contributing significantly to genetic diversity.

Step-by-step explanation:

Independent assortment explains why a collection of meiotic products that includes gametes of genotype Ab will also include gametes of genotype AB in roughly the same proportion. This principle is crucial to understanding how genetic variation occurs during sexual reproduction.

Independent assortment occurs during the first division of meiosis, specifically in anaphase I, where homologous chromosomes are randomly distributed to daughter cells, leading to gametes with unique combinations of chromosomes. Mendel's law of independent assortment states that each pair of alleles segregates independently during gamete formation, leading to every possible combination of alleles being equally likely. Because of this, for an organism with genotype AaBb, the possible gametes are AB, Ab, aB, and ab, each with an equal probability of being formed.

The genetic diversity produced by independent assortment is enhanced by random fertilization, where each gamete, with its unique chromosome combination, can fuse with another gamete with its unique combination, leading to vast potential variations in offspring. This is further evidenced in the dihybrid cross, where true-breeding parents with different traits produce offspring with a combination of these traits expressed in unique proportions in the subsequent generations, conforming to Mendel's principles.

Answer 2

d .

Explanation:

1. The law of Independent assortment say that the formation of combinations of chromosomes in meiosis is random, which says that each pair of homologous chromosomes are independently separated.

2. No pair of chromosome is dependent on another pair of chromosomes.

3. In independent assortment, the cell containing allele AaBb produce equal amount of gametes AB, Ab, aB, and ab.
