Answer:
When homologous chromosomes form pairs during prophase I of meiosis I, crossing-over can occur. Crossing-over is the exchange of genetic material between homologous chromosomes. It results in new combinations of genes on each chromosome. ... It is obviously another source of genetic variation in offspring.

18 chromosomes would be in each of its gametes.
What are chromosomes?
the nucleus of most living cells contains a threadlike structure made of nucleic acids and proteins that carries genetic information in the form of genes.
There are 23 pairs of chromosomes in humans. The chromosome's distinctive structure helps to increase the integrity of the DNA while also keeping it securely packed with histone proteins to fit within the cell. For instance, a single cell's DNA will be 6 feet long when unraveled; from this, it is clear why each cell's nucleus needs to be packaged.
according to the given information:
number of chromosomes: 36
36√2 is 18
18 chromosomes would be in each gamete.

Secondary immunodeficiency is a deficiency or defect in body's immune system.
10 common diseases that can cause a secondary immunodeficiency are:
leukemia
diabetes
skin cell diseases
burns
virus infection
lymphoid malignancy
nephrotic syndrome
neutropenia
human immunodeficiency virus
protein-calorie malnutrition
There is no known way to prevent inherited immunodeficiency disorders. but there is some ways to prevent infection like get enough sleep, keep clean, manage stress, eat right etc.
Answer:
Plasma.
Explanation:
Plasma is the liquid component or constituent of the blood after the removal of all the cells and platelets. It is composed of 90% water, coagulation factors like antibodies, electrolytes, proteins , lipids e.t.c which help to maintain the blood PH and osmotic balance of the blood during the process of giving viscosity to the blood. The plasma comprises of 55% of the blood.
Answer:
failure of a pair of homologous chromosomes to separate in meiosis I, failure of sister chromatids to separate during meiosis II, and failure of sister chromatids to separate during mitosis. Nondisjunction results in daughter cells with abnormal chromosome numbers (aneuploidy).
