In studying the gene pool of a population, you find that 15% of the population is homozygous recessive (tt) for a trait. how would you use this information to solve for the frequency of the dominant t allele?

%

Explanation:

As per HARDY-WEINBERG LAW

represents the frequency of the dominant allele in the population

represents the frequency of the recessive allele in the population

represents the percentage of homozygous dominant individuals

represents the percentage of homozygous recessive individuals

represents the percentage of heterozygous individuals

Here the frequency of ‘tt” allele is

Thus,

Substituting this in below given equation, we get -

Frequency of T allele is represented by q.

Thus, frequency of T allele would be %

nucleic acid molecules are incredibly complex, containing the code that guarantees the four different nucleotide units comprise dna, the nucleic acid of interest to the genealogist. and one of four nitrogen-containing molecules called nucleotides

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
