The frequency of two alleles in a gene pool is 0.1 (A) and .9 (a). What is the percentage in the population of heterozygous in individuals? of homozygous recessives?

Answers

The frequency of two alleles in a gene pool is 0.1 (A) and .9 (a). The percentage in the population of heterozygous in individuals is 18%, and the percentage of homozygous recessives is 81%.

The frequency of two alleles in a gene pool is 0.1 (A) and .9 (a). Hence,

p = 0.1 and q = 0.9

The equation for the Hardy-Weinberg principle is:

p² + 2pq + q² = 1

p² + 2pq represents the frequency of heterozygous individuals and q² represents the frequency of homozygous recessives

Substituting the values:

p² + 2pq + q² = 11 × 0.01 + 2 × 0.1 × 0.9 + 0.81 = 1 = 0.01 + 0.18 + 0.81= 1

Therefore, the percentage of heterozygous in individuals is:

p² + 2pq = 0.18 × 100% = 18%

And the percentage of homozygous recessives is:

q² = 0.81 × 100% = 81%

Thus, the percentage in the population of heterozygous individuals is 18%, and the percentage of homozygous recessives is 81%.

hey its p(A) = 0.1 and q(a) = 0.9
The percentage in the population of heterozygous individuals:
2pq = 2 x 0.1 x 0.9 = 0.18 = 18%

As set of overlapping DNA fragments that form a contiguous stretch of DNA is called aA) chromosome.
B) sequence.
C) map.
D) contig.

Answers

the answer is D) contig

Acontiguous stretch of DNA formed from overlapping DNA fragments is known as a contig. Contigs are a crucial component in DNA sequencing and genome assembly.

A set of overlapping DNA fragments that form a contiguous stretch of DNA is referred to as a contig. In molecular biology and genetics, contigs are used in the process of DNA sequencing to assemble larger sequences of DNA from smaller sequences or fragments. Creating a contig is a crucial step in genome assembly, and it is typically accomplished using computer algorithms that match overlapping ends of different DNA fragments.

what might happen to a native fish species if an introduced fish species that ate the same foods was released in the pond?

Answers

well the native species might have a possibility of going endangered (in that specific community)

they will obviously compete with the introduced species, but you have to take into consideration that predators who eat fish might prefer one over the other, and how fast each species reproduces
