The man with blood type  A might have one of two genotypes:
1. Iᵃ  Iᵃ<span> 
2. </span>Iᵃ  i
In this case, Iᵃ is an allele for A group, and i is an allele for 0 group.
The ABO blood type is controlled by a single gene (the ABO gene) with three types of alleles (Iᵃ   Iᵇ    and   i)

How can a rise in temperature cause a change in a polar ecosystem
Dvinal [7]

Sea levels would rise.

Increase in temperature (for example due to global warming) increases the rate of melting of polar ice.

Consequently, the sea levels of the polar ecosystem would increase.

In addition, the melting of the ice caps also increases the temperature of the water in the oceans. As a result, the water expands which also increases the sea levels.

Two genes (R or r) and (D or d), each with a dominant and recessive allele, are
Andrej [43]

Answer:

B. DR, Dr, Rd, dr

Explanation:

This question involves two genes. Alleles D and R are dominant over alleles d and r. These two genes obey the law of independent assortment as proposed by Gregor Mendel.

Based on the question, a genotype RrDd will produce the following combination of gametes following the process of meiosis:

DR, Dr, dR, dr

In which stage of the Calvin cycle does the plant cell produce energy for storage?
Ludmilka [50]
I believe the answer is the Regeneration stage.
A this stage of the Calvin Cycle, only one of the G3P molecules leaves the cycle and is sent to the cytoplasm to contribute to the formation of other compounds needed by the plant. Because the G3P exported from the chloroplast has three carbon atoms, it takes three "turns" of the Calvin cycle to fix enough net carbon to export one G3P. Each turn makes two G3Ps, therefore three turns make six G3Ps.

A pea plant is heterozygous for both seed shape and seed color. S is the allele for the dominant, spherical shape characteristic
kati45 [8]

So, you would make a punnet square. You would put the capital S and lowercase s on the top of it and then the capital Y and lowercase y on the side. Then you should have SY, sY, Sy, and sy as your outcomes.
