How do the random distribution of chromosomes and crossovers create more variation in the resulting gametes?

When cells divide during meiosis, homologous chromosomes are randomly distributed during anaphase I, separating and segregating independently of each other. This is called independent assortment. It results in gametes that have unique combinations of chromosomes.

<em>Crossing over creates new combinations of genes in the gametes that are not found in either parent, contributing to genetic diversity.</em>

Archy [21]
The answer is <span>Conduct a test cross with a purebred recessive plant. 

</span>

Test cross is the cross between an organism with unknown dominant genotype and an organism with known recessive genotype.

<span>Since dominant trait results from a dominant allele, the test cross can determine if an unknown genotype is heterozygous and homozygous dominant. </span>

If A is dominant allele, and a is recessive allele, then AA is dominant homozygote, Aa is a heterozygote, and aa is recessive homozygote.

<span>According to the Punnett square, if all of the offspring are heterozygote (Aa), then unknown genotype is dominant homozygous (AA). If half of the offspring are the heterozygote, and the other half are recessive homozygote, then the unknown genotype is heterozygote (Aa).</span>
