Question 8 4 pts Many organisms are hermaphroditic and make both eggs and sperm. If a single individual self-fertilized (contributed both the ess and sperm), would the resulting offspring be genetically identical to the parent? If not what contributes to the diversity? Explain your answer. BIVA-A-I EX31XXE - ? VOGT 12pt • Paragraph O words

Answer 1

In case of hermaphrodites, the progenies will not be identical to each other and not even to the parent cell. They will be different from each other. This is because during the formation of gametes while meiosis, the process of independent assortment and crossing over take place.

Crossing over is the process of genetic material between non sister chromatids of homologous chromosomes. It occurs during prophase 1 of meiosis 1. It results in the formation of recombinant chromosomes which are not only different from each other but are also different from the parent chromosomes.

Independent assortment is there separation of alleles of different genes from each other in an independent manner so that every gamete receives one allele of a gene. It occurs during metaphase 1 of meiosis 1.

Once the gametes are formed, they fertilize in a random manner. The random fertilization gives rise to millions of combination of gametes giving rise to different types of zygotes. Because of random fertilization and crossing over and independent assortment, the progeny of same parent are different from each other and also from the parent itself.
