Karyotypes can be studied to determine an organism’s chromosomal makeup and to detect genetic defects. patau syndrome occurs when an individual has an extra copy of chromosome 13, giving them three copies. symptoms of patau syndrome include extra digits, seizures, and cleft palate. which word would geneticists use to describe the cause of patau syndrome?

The answer is trisomy 13.

Trisomy 13 is a condition in which an extra copy of chromosome 13 is present. Instead of two chromosomes 13 in a cell, there are three chromosomes. This is a consequence of a failure of chromosome 13 to separate during the gamete development. Thus, an egg cell or a sperm cell will have two instead of one chromosome 13 and after a cross with normal gamete cell, a zygote will have three chromosomes 13.

answer: b: experiments that showed that all cells are similar in how they metabolize and in their composition

explanation:

not only is it colder, it also becomes darker, less salty, and more dense.
