Chromosome 21 figure D is the result of a process known as________
Softa [21]

Answer:

Chromosome 21 in figure D is the result of a process known as non-disjunction

Explanation:

Meiosis is the process of cell division that serves to obtain gametes, cells with exactly half the chromosome load of the species. This process involves the equal distribution of chromosomes in each daughter cell.

Non-disjunction is an alteration in the separation of the sister chromatids during meiosis, resulting in a gamete with non-separated sister chromatids, which when joined to a normal gamete can produce an organism with an extra chromosome.

In the karyotype shown in the photo, the non-disjunction in chromosome 21 produces a trisomy, a type of aneuploidy seen in Down syndrome.

Even if reproduction between species leads to conception, the embryo may not be able to survive to maturity or will be sterile. This ensures that species remain integral by restricting gene flow.
