Phenylketonuria (PKU) is a disease caused by a recessive mutation. PKU is extremely common in Ireland, affecting approximately 1
aleksklad [387]

Answer:

97%

Explanation:

PKU is caused by a recessive mutation, which means that affected individuals are homozygous and recessive (<em>tt</em>).

<u>The frequency of genotypes according to Hardy-Weinberg equilibrium is:</u>

TT= p^2\\Tt=2pq\\tt=q^2

where p is the frequency of the <em>T</em> allele and q is the frequency of the <em>t</em> allele.

Affected individuals are 1 in 4500, which means the frequency of <em>tt </em>genotype is 1/4500.

If the population is in Hardy-Weinberg equilibrium,

q^2=1/4500\\q=\sqrt{1/4500} \\\\q=0.015

The sum of the allele frequencies adds up to 1, therefore:

p + q = 1

p= 1 - q

p= 1 - 0.015

p= 0.985

The frequency of the TT genotype (homozygous wild-type individuals) will be:

p^2=0.985^2\\p^2=0.97

97% of the population will have the homozygous wild-type TT genotype.

List and describe the functions of carbohydrates in the body. Explain how the body maintains glucose levels, including which hor
kicyunya [14]

Answer:

There are different function performed by carbohydrates in the body like-

Storage: When there is excess glucose present in the body they are stored as glycogen in muscles and liver.

Providing energy: Carbohydrates are the primary source of energy for the cells present in our body.

Carbohydrate helps to spare proteins and lipids and helps in providing polysaccharides for membrane carbohydrates.

The body maintains blood glucose levels through hormones. For example, when the blood glucose level gets high insulin is released in the blood by the pancreas which reduces the blood glucose level by accumulating glucose as glycogen in the liver and muscle.

Glucagon works opposite to insulin and increases the blood glucose level.
