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

Drag each circle to the correct location on the image. Each circle can be used more than once, but not all circles will be used.
Rina8888 [55]
Briefly, one can categorize the 3 types of boundaries as so: At convergent boundaries, the two tectonic plates are coming closer to each other; at divergent boundaries they are increasing they move away from each other and at transform boundaries the plates are moving parallel to their boundary. Based on this, all boundaries will be divergent boundaries.

Describe the energy pyramid describe the biomass pyramid
kogti [31]
The energy pyramid describes decomposers compared to energy lost as heat. Primary producers start at 100% and it decreases to 10% at primary consumers, 1% at secondary, .1% at third level, and .01% at apex.
The biomass pyramid describes the total mass of an organism and as a biomass moves up, the overall mass is losing volume. This means it decreases as it moves from the bottom to the top.

A population of prairie dogs lives at the edge of a meadow.
Shalnov [3]

Answer:

B. They belong to the same species and C. They live in the same area.

Explanation:

This is an educated guess. If you think about it, if there was a population of humansss, we dont have the same parents nor the exact genes so to only two that make sense is those to (^ω^)
