A survey reveals that 25 percent of a population of 1,000 individuals have attached earlobes (are homozygous recessive for the t
Mumz [18]

Answer:

d. pxp +2pq

Explanation:

The formula for genotype frequency for a population in Hardy-Weinburg equilibrium is as under:

                           p² + 2pq + q² = 1

where, p = dominant allele

           q = recessive allele

Here,

 p² represents frequency of homozygous dominant genotype

2pq represents frequency of heterozygous genotype

q² represents frequency of homozygous recessive genotype

Also, although the genotypes p² & 2pq are different from each other yet phenotypically they both will collectively produce dominant trait i.e. free ear lobes not attached earlobes. So the term "p² + 2pq or pxp + 2pq" represents the frequency of the individuals who show the dominant phenotype in this particular population. Dominant phenotype will comprise 75% of the population.

A sodium atom has one outer electron, and a carbon atom has four outer electrons. How might this difference be related to the ty
fredd [130]
<span>The number of electrons in the valence shell of an element is the principal determinant factor of the kind of chemical bonding it will be involved in. For an element that has only one electron in its outermost shell, such an element will donate the electron to another element which need only one electron. Thus, such an element will undergoes electrovalent bonding. For an element which have four electrons in its outermost shell, such element will prefer to share the electrons will other elements who need such in order to become stable, thus, such element will undergo covalent bonding.</span>
