Answer:
using multiple origins of replication on each chromosome
Explanation:
Answer:
a. Stabilizing selection
Explanation:
Babies lower than 5.5lbs would suffer from various disorder because of low birth weight as their body would not be able to compete as well they would have weak immune system and malnourishment. Whereas high birth weight carry the equally above risk as their body wont be able to cope up and organs become insensitive to various hormones. for the survival the birth weight should be within a median range so that it would be favorable for themselves and surroundings.
Stabilizing selection occurs when a population stabilizes on a particular trait value and genetic diversity decreases. As in this example, an average baby weight has to favour against extreme variation for it's better survival.
therefore, this is an example of stabilizing selection.
Recessive genetic disorders result from inheriting 2 defective recessive alleles of gene ( one from each parent ). The x - chromosome holds about 10% of all human genes. Sex chromosomes are: males XY, females XX. Y-traits occure in males only. Y-disorders are rare.
Answer: Most recessive disorders are on the Autosomal recessive gene, and thus not x-linked.
Answer:
true
Explanation:
Diabetes is a serious health condition that impacts the way our body assimilates sugar, which is an important energy source for our body. Different field of studies have come up with reports suggesting that poor dietary habits and some sort of inactivity could trigger the onset of the disease.
In order to maintain the required healthy lifestyle to keep the disease away, people are required to eat healthy foods, devoid of too much fats and calories but must be rich in fibre. There should also be between 30 – 60 minutes of moderate physical activity. If one is also overweight, 5-10 percent of the body weight can be removed to reduce the risk of the disease.
