Human albinism is an autosomal recessive trait. Suppose that you find a village in the Andes where 1/4 of the population is albi
Aleks04 [339]

Answer:

500

Explanation:

According to the given information, the total number of albino people in the population= 1000/4 = 250.

Since albinism is an autosomal recessive trait, the genotype of albino people would be homozygous recessive. Therefore, the frequency of homozygous recessive genotype in the population (q2) = 250/1000= 0.25.

The frequency of recessive allele (q) = square root of 0.25 = 0.5

Since p+q=1. So, p (frequency of dominant allele) = 1-q = 1-0.5 = 0.5

Frequency of heterozygotes in the population= 2pq = 2 x 0.5 x 0.5 = 0.5 or 50%

Therefore, expected number of heterozygotes in the given population= 50% of 1000 = 500

neonofarm [45]

Answer:

Carbohydrates are used by the body for energy and structural support in cell walls of plants and exoskeletons of insects and crustaceans. They are made of smaller subunits called monosaccharides. Monosaccharides have <u>carbon</u>, <u>hydrogen</u>, and <u>oxygen</u> in a 1:2:1 ratio.

Difinition of disaccharides: any of a class of sugars whose molecules contain two monosaccharide residues.

Make an example...

Short carbohydrate chains are called <u>oligosaccharides</u> and contain 3 to 10 sugar molecules. Long carbohydrate chains can contain hundreds or even thousands of monosaccharide units. molecule of <u>glucose</u> and one molecule of <u>fructose</u> joined together.
