The name comes from a latin word meaning to glue or bind together. DNA ligase catalyses the joining of DNA fragments (usually those produced by restriction enzymes). Thus different genes can be put into vectors and moved into other hosts.

if there are 500 people in a population, and 150 are homozygous HbA/hba, 150 are homozygous hbs/hbs, and 200 are heterozygous hb

sineoko [7]

Answer:

$0.547$

Explanation:

Given -

Total Population - $500$

Individuals with homozygous HbA/hbA genotype - $150$

Individuals with homozygous hbs/hbs genotype - $150$

Individuals with heterozygous hba/hbs genotype - $200$

Let us assume the given population is in Hardy Weinberg' equilibrium

The frequency of individuals in the given population with homozygous HbA/hba genotype is equal to number of individuals with homozygous HbA/hba genotype divided by total population.

$\frac{150}{500} \\= 0.3$

The frequency of hba allele is equal to

$\sqrt{0.3} \\= 0.5477$
