Topsoil is usually eroded first because it is made of small, lighter particles. Topsoil is a very useful layer of the soil that is filled with nutrients. This layer where plants grow. The best quality of soil allows for the smooth growth of plants and trees. Topsoil should be soft and made in small and light particles so that the roots can grow below it.

In a hypothetical population of plants, flower color is determined by a single gene with two alleles. In a population of 500 pla

Answer:

In the F1 generation

RR = 0%

Rr = 50% (or 0.5)

rr = 50% (or 0.5)

Explanation:

A pink flowering plant has the genotype Rr. It is heterozygous for the allele. The alleles for this gene appears to show incomplete dominance, as the heterozygous phenotype is a blend of the two homozygous genotypes.

A white flowering plant has the genotype rr. It is homozyogous for the white allele

A punnet square of the cross is shown.

The resulting punnet square shows that only Rr and rr genotypes are possible, at a ratio of 50:50 (or 1:1). Therefore, the genotype frequency of Rr is 50%, and rr is 50% in the F1 generation. This can also be written as 0.5. It is not possible to get a red plant, as the genotype RR can not come from this cross
