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

Given what you know about the endosymbiotic theory, which region of the chloroplast below would you expect to be derived from th
san4es73 [151]

Answer:

Photosynthetic lamellae

Explanation:

The cyanobacteria were the first successful photosynthetic cells present on the Earth which were able to convert the light energy into the chemical energy.

The endosymbiosis theory suggested that these cyanobacteria were engulfed by the eukaryotes and the cyanobacteria get transformed into the chloroplast.  

The region of the chloroplast that was formed in the cyanobacteria before the endosymbiosis happened was the photosynthetic lamellae which contained the chlorophyll molecule and thus is the correct answer.

Thus, Photosynthetic lamellae are the correct answer.
