What causes genetic variation in a population
Gre4nikov [31]

Answer:

A lot of factors cause genetic variation in a population. The root of all genetic variation is mutations, which occur randomly.

A lot of genetic variation in fact results during meiosis, the process by which gametes (sex/reproductive cells) are formed. The 3 main ways are crossing over, independent assortment of chromosomes, and random fertilization. Crossing over occurs during Prophase I of meiosis, in which genetic material is exchanged between nonsister chromatids of homologous chromosomes. Independent assortment refers to the following: When cells divide during meiosis, homologous chromosomes are randomly distributed during anaphase I, separating and segregating independently of each other.  Random fertilization is where any sperm can fertilize any egg cell. The many combinations of eggs and sperms mean variation.

Another source of genetic variation include gene flow. Gene flow is where populations have their members enter other populations (migration), influencing the gene pool of populations. This source is more controversial, however.

Random mating can also increase genetic variation.

Hyperthyroidism Hyperthyroidism decreases protein synthesis. slows heart rate. decreases oxygen consumption. causes cold intoler
Alex777 [14]

Hyperthyroidism decreases protein synthesis, increases heart rate, increases oxygen consumption, and increases protein catabolism.

<h3>What is Hyperthyroidism and its effect on the body?</h3>

  • Hyperthyroidism occurs when the thyroid gland produces too much of the hormone thyroxine.
  • Hyperthyroidism can accelerate body metabolism, causing unintentional weight loss and a rapid or irregular heart rate.
  • Hyperthyroidism is the catabolic state with increased energy expenditure, lipolysis, and protein turnover.
  • Increased protein turnover includes increased protein breakdown and reduced serum protein level.
  • Hyperthyroidism increases oxygen consumption to meet the body's requirements due to increased basal metabolic rate.
