Question

Nullisomics produce which type of gametes?; 1) n-1; 2) n+1; 3) n; 4) n+1-1

Answer 1

Nullisomics produce (1) n-1 type of gametes.

Explanation:

1.Nullisomic is a genetic condition involving the lack of both the normal chromosomal pairs for a species (2n-2). Humans with this condition will not survive.

2.Aneuploidy is a chromosomal variation due to a loss or a gain of one or more chromosomes resulting in the deviation from the normal or the usual number of chromosomes. The different conditions of aneuploidy are nullisomy (2N-2), monosomy (2N-1), trisomy (2N+1), and tetrasomy (2N+2).

3.Nullisomy is caused by non-disjunction, during meiosis that causes two of the gametes to have no chromosomal material, leaving the other two gametes to have double the amount of chromosomal material (disomic).

4.Due to the lack of genetic information, the nullisomic gametes are rendered unviable for fertilization

Nullisomics produce (1) n-1 type of gametes.
