The table above shows five different types of chromosomal abnormalities that can occur during meiosis. they result in either an individual having too many or too few chromosomes in their genome. what is the most likely cause of these chromosomal abnormalities?

The correct answer would be nondisjunction.

Nondisjunction refers to the failure or improper division of chromosomes during a cell division.

It can occur in meiosis I, meiosis II as well as in mitosis.

In anaphase I of meiosis I nondisjunction results in improper segregation of homologous chromosomes due to which one cell gets two copies of the chromosome and other cell does not get a single copy of that chromosome.

Similarly, in anaphase II, the sister chromatids are improperly divided due to nondisjunction. It results in a situation in which one daughter cell posses an extra copy of the chromosome while the daughter cell lacks that chromosome.

For example, in Down syndrome trisomy of chromosome 21 occurs due to nondisjunction.

i'm gonna put a couple so you can chose from

explanation:

if you know the fur color of the offspring mice, you can use the ratios to identify the genotypes of the parents.

if either parent mouse passes a dominant allele, the offspring will have black fur.

if the parental mice has two different fur color (i.e white and black) , the color of the offspring's fur would be either black, white, or the combination of both (grey)

hope this : )
