A population is in Hardy-Weinberg Equilibrium with respect to a gene, "yellow," which has 2 alleles, y and Y. Y, the wild type a
Anton [14]

Answer:

The frequency of the Y allele is 0.7

The frequency of the y allele is 0.3

The frequency of the YY homozygote is 0.49

The frequency of the Yy heterozygote is 0.42

Explanation:

According to Hardy-Weinberg Equilibrium,

p + q = 1

p² + 2pq + q² = 1

where,

p = frequency of dominant allele

q = frequency of recessive allele

p² = frequency of dominant homozygous genotype

2pq = frequency of heterozygous genotype

q² = frequency of  recessive homozygous genotype

Here,

yy = q² = 0.09

frequency of y allele = q = √0.09 = 0.3

frequency of Y allele = p = 1-q = 1-0.3 = 0.7

p² = YY = (0.7)² = 0.49

2pq = Yy = 2 * 0.7 * 0.3 = 0.42

Maggots get their energy by breaking down dead and decaying animals. What are maggots? autotrophs producers decomposers heterotr
nika2105 [10]

Food is the source of energy that is used by the organism for the process of metabolism. Maggots are the larva of flies and depend on dead and decaying matters.

Maggots are:

Option C. Decomposers

This type of organism can be explained as:

  • The organism is classified into different classes according to the nature of its feeding habits.

  • <u>Autotrophs </u>are called the primary producer and break inorganic compounds into organic for energy.

  • <u>Producers </u>are the organism that produces their food by converting solar energy into chemical energy.

  • <u>Decomposers </u>are small-sized organism that lives in soil and breaks the organic compound of dead and decayed bodies.

  • <u>Heterotrophs </u>are organism that depends on other sources and producers for energy.

Therefore, maggots are decomposers.
