svetoff [14.1K]

Vilka [71]

Answer:

1 monosomy

2 trisomy

3 Down syndrome

4 Turner syndrome

5 non-disjunction

6 metaphase

7 twenty-two

8 largest (chromosome 1)

9 smallest (chromosome 22)

10 karyotype

Explanation:

Non-disjunction during meiosis I or II occur when homologous chromosomes or sister chromatids refuse to separate. This makes the resulting gametes to have too many or too few chromosome numbers in their genomes.

A gamete with too few chromosome number that participates in fertilization with a normal gamete will result in a zygote with abnormally less chromosome number. This situation is referred to as monosomy. Whereas, the fusion of a gamete with too many chromosome number with a normal gamete will result in a zygote with too many chromosome, a situation known as trisomy.

The manifestation of monosomy and trisomy in humans results in Turner and Down syndromes respectively.

Humans have 23 pairs of chromosomes out of which a pair determines maleness or femaleness - the sex chromosome. Other chromosomes are referred to as autosomes. Hence, there are 22 autosome pairs and 1 pair of sex chromosome.

Chromosomes are studied by karyotyping, a process that involves photographing chromosomes at the metaphase stage of the cell cycle, cutting them out, and then arranging them in decreasing order of size.
