The ABO blood groups in humans are expressed as the IA, IB, and i alleles. The IA allele encodes the A blood group antigen, IB e

ncodes B, and i encodes O. Both A and B are dominant to O. If a heterozygous blood type A parent (IAi) and a heterozygous blood type B parent (IBi) mate, one quarter of their offspring will have AB blood type (IAIB) in which both antigens are expressed equally. Therefore, ABO blood groups are an example of:
multiple alleles and incomplete dominance
codominance and incomplete dominance
incomplete dominance only
multiple alleles and codominance

Answer:

Multiple alleles and codominance

Explanation:

Co dominance may be defined as the phenomena in which both the alleles can express themselves independently in heterozygous condition. The involvement of more than two alternative form of a single gene is known as multiple allele.

The ABO blood group represent the example of codominance and multiple allelism. In case of AB blood group both the alleles I(A) and I (B) express themselves in heterozygous condition and result in the formation of AB blood group. Different alleles like I(A), I(B), I(A)I(B),i are involved in case of ABO blood group, this shows multiple allele.

Thus, the correct answer is option (4).

It would be B.) ospreys; decomposers

Since ospreys eat nothing but fish, if all of the trout died from a disease, the ospreys wouldn't have anything to eat because all of the fish are dead. This results in a loss of energy for the ospreys.

However, decomposers would gain more energy because they gain their energy from dead creatures, in this case, it would be the trout.

Leokris [45]

Mature and established trees die for a combination of reasons but sudden browning of foliage is typically associated with a lack of water supply to the canopy. Water supply can be cut off to the canopy due to obvious issues including deficiency or root damage.

<h3>What is Carbon?</h3>
  • Carbon is a chemical component with the symbol C and atomic number It is nonmetallic and tetravalent—its atom makes four electrons unrestricted to form covalent chemical bonds. It belongs to group 14 of the periodic table. Carbon produces up only about 0.025 percent of Earth's crust.
  • Carbon is employed in some way in almost every industry around the globe. It is used for fuel in the form of coal, methane gas, and crude oil (which is used to produce gasoline). It is used to make all sorts of fabrics including plastics and alloys such as steel (a mixture of carbon and iron).
  • Carbon is a chemical element with the symbol C and atomic number 6. Categorized as a nonmetal, Carbon is a solid at room temperature.
