Fossil Record - Provides proof by exposing the details of a ancestor for compared to the living one.
Geographical Distribution of Living Things - a pattern of the ancient existing species, isolated land and islands have their own species of plants and even some animals.
Similarities in Development - Charles Darwin used the science of embryology to test many species within a class to find out that they are similar even if the adult version looks completely different.
Molecular Similarities - its believed that natural selections isn’t the reason for evolution actually its the genetic drift of mutant alleles that are neutral.

In a hypothetical population of plants, flower color is determined by a single gene with two alleles. In a population of 500 pla
blondinia [14]

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

kari74 [83]

[ C. Coriolis Effect ]

If the Earth didn't rotate, winds would travel north or south because of the differences in pressure and temperature. The Earth does rotate, so, the Coriolis Effect diverts the wind to the left of the Southern Hemisphere and right of the Northern Hemisphere. The Coriolis Effect is very important because it creates cyclonic weather system.s

Best of Luck!
