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

E.Coli would be a good model organism to study how the cell membrane controls movement of substances in and out of cells?
hodyreva [135]

Answer:A.) True

Explanation:

E.Coli would be a good model organism to study how the cell membrane controls movement of substances in and out of cells because  it a eubacteria .Eubacteria characteristics include the ability to allow the movement of molecules across its membrane once a proton gradient is established , The membrane also has permeability enhancing properties that allow for the easy movement of substances.

What will happen to the frequency of the recessive allele for the hbs gene when there is an outbreak of malaria? the frequency w
Ad libitum [116K]

In the outbreak of malaria, the frequency of the recessive allele for the HbS gene will increase. The correct option is A.

<h3>What is the HbS gene?</h3>

HbS is a beta-globin gene known as sickle hemoglobin.

It causes sickle cell disease in humans.

The disease is expressed by two HbS variants or one HbS variant or one another beta-globin gene.

Malaria is caused by the plasmodium parasite, which is present in the saliva of the mosquito.

Thus, the correct option is A, the frequency will increase.
