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.

Competition  help to regulate population growth since only those who are able to obtain food survive.

Crop plants and weeds may compete for water and for sunlight.

Farmers spray herbicides early in the growing season to avoid competition between crop plants and weeds.

<h3>What is the effect of competition on population?</h3>

Competition among species help to regulate population growth by ensuring that only those who are able to obtain food survive. Thus, only fit individuals of a species survive.

Crop plants and weeds may compete for water because water enables them to carry out metabolic activities of growth and development.

Crop plants and weeds may also compete for sunlight and they need sunlight to carry out photosynthesis.

Farmers spray herbicides early in the growing season in order to avoid or reduce competition between crop plants and weeds.

In conclusion, competition among species helps to control overpopulation.
