Answer/Explanation:

Mendel could have crossed a true breeding (homozygous) brown fly with a true breeding (homozygous) black fly. BBx bb. The resulting offspring would all be Bb (heterozygous). If brown body color is dominant to black body color, all of these heterozygous flies would always be brown. This is because the brown allele is displayed over the black allele.

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.

When a lunar eclipse happens, which would we not see: the sun or the moon?
Nookie1986 [14]

Answer:

the sun

Explanation:

The typical lunar eclipse happens when the Sun, Earth and moon are all aligned 180 degrees apart from each other in the sky. When this happens, the Earth casts a shadow onto the moon, so the Sun should not be visible at all if you can still see the moon.
