Question

_______ has gametes with duplications and deletions which leads to semisterility. Separation of information occurs. Two gametes that are missing and have extra copies of info. If these gametes participate then birth defects, lethality and semiysterility occurs.

Answer 1

Nondisjunction during meiosis can result in gametes with duplications and deletions of genetic information, leading to semisterility. This can cause birth defects, lethality, and other genetic disorders.

Step-by-step explanation:

Nondisjunction is a biological phenomenon that occurs during meiosis, the process of cell division that produces gametes. It refers to the failure of homologous chromosomes or sister chromatids to separate properly, resulting in gametes with an abnormal number of chromosomes. This can lead to disorders known as aneuploidy, which can cause birth defects, lethality, and semisterility. For example, if homologous chromosomes fail to separate during meiosis I, two gametes will lack that particular chromosome and two gametes will have two copies of the chromosome.
