Question

which of the following diagrams show how meiosis allows an organism to form gametes that include alleles from both of its biological parents? choose 2 answers: a diagram, b diagram, c diagram

Explanation:

• Option A: This diagram shows crossing - over (recombination) between homologous chromosomes (one from each parent, represented by different colors). During crossing - over in meiosis, genetic material is exchanged between non - sister chromatids of homologous chromosomes. This process results in gametes that have alleles from both parents, as the chromosomes now carry a mix of genetic information from the maternal and paternal chromosomes.
• Option B: This diagram represents the process of meiosis where homologous chromosomes (from each parent) separate and then sister chromatids separate. The resulting gametes have a combination of chromosomes (and thus alleles) from both parents. The initial cell has chromosomes from both parents (different colors), and through meiosis, the gametes end up with a mix of these parental alleles.
• Option C does not show a process that leads to gametes with alleles from both parents in the context of meiosis for forming gametes with mixed parental alleles. It seems to show a different stage of cell division or a non - meiosis - related process for generating gametes with mixed parental alleles.

Answer:

A. Diagram showing crossing - over between homologous chromosomes (different colored chromosomes exchanging genetic material)
B. Diagram showing meiosis with separation of homologous chromosomes (from different parents) and then sister chromatids to form gametes with mixed parental alleles
