Which Statement Describes How The Shown In The Diagram Results In New Inheritable Genetic Combinations class=

Answer:

Certainly! During meiosis, genetic recombination occurs through crossing over between homologous chromosomes. This process leads to new combinations of alleles, resulting in genetic diversity among offspring.

Explanation:

Certainly! The process shown in the diagram results in new inheritable genetic combinations through genetic recombination during meiosis. Here’s how it works:

Homologous Chromosomes Pair Up: During meiosis, homologous chromosomes (one from each parent) pair up to form a structure called a tetrad.

Crossing Over and Exchange: Within the tetrad, the chromosomes can cross over. This involves the physical exchange of genetic material between chromatids. As a result, sections of DNA are swapped between homologous chromosomes.

New Allele Combinations: The exchanged genetic material leads to new combinations of alleles on the same chromosome. Although the same genes appear in the same order, the alleles are different. These new combinations explain why offspring from the same parents can look so different1.
