Identify two means by which meiosis results in genetically unique gametes, and explain why this is important.

Biology
1 answer:
Rashid [163]3 years ago
8 0

Explanation:

Meiosis is beneficial as it produces gametes that are genetically different to the parent cell, and when the gametes combine the offspring produced is made from combination of genes from both mother and father. The offspring is genetically unique, there is no other organism on the Earth with the exact same DNA sequences on their chromosomes.

The majority of cells in a human body go through mitosis and not meiosis. Is this true or false?
Andru [333]

Answer:

True

Explanation:

Mitosis results in two cells that are genetically identical. DNA replication only occurs during "S phase." Meiosis is commonly defined as a type of cell division that divides a somatic cell and produces four gamete cells when doing so.

<u><em></em></u>

<u><em>S phase:</em></u> In S phase, the cell synthesizes a complete copy of the DNA in its nucleus. It also duplicates a microtubule-organizing structure called the centrosome. The centrosomes help separate DNA during M phase.

<u><em>Gametes</em></u> are an organism's reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome.
