<h3>Chemical bond is the answer. </h3>

Explanation:

A chemically bond is defined as the invisible force between two atoms which together forms a molecule. Chemical bonds are of different types - covalent bond and ionic bond. These bonds are formed between the atoms because of a chemical reaction.

In a chemical reaction, different reaction intermediates are formed which leads to the formation of new forces of attraction between nearby atoms or ions to form new bonds. Thus chemical bonds are formed from chemical reaction.

Suppose a population is carrying a condition controlled by two alleles: P (dominant) and p (recessive). Only homozygous individu

Virty [35]

The answer is B. 72.25 percent.

The Hardy-Weinberg principle can be used:

p² + 2pq + q² = 1 and p + q = 1

where p and q are the frequencies of the alleles, and p², q² and 2pq are the frequencies of the genotypes.

The p allele (q) is found in 15% of the population:
q = 15% = 15/100
Thus, q = 0.15

To calculate the P allele frequency (p), the formula p + q = 1 can be used:
If p + q = 1, then p = 1 - q
p = 1 - 0.15
Thus, p = 0.85

Knowing the frequency of the P allele (p), it is easy to determine the frequency of the PP genotype (p²):
p² = 0.85² = 0.7225

Expressed in percentage, p² = 72.25%.

Red and white show incomplete dominance

Incomplete dominance is a form of intermediate inheritance in which one allele for a specific trait is not completely expressed over its paired allele. This results in a third phenotype in which the expressed physical trait is a combination of the phenotypes of both alleles.

Hope this helps! I'm happy to help with any other questions you might have :)
