How is codominant inheritance different from incomplete dominant inheritance?a. In codominance, two alleles are expressed equally; in incomplete dominance, there is only one allele in the system.b. In codominance, one gene is recessive to two dominant genes; in incomplete dominance, all genes are recessive.c. In codominance, the two alleles cooperate to make an intermediate phenotype; in incomplete dominance, the heterozygote shows the recessive phenotype.d. In codominance, two alleles are expressed equally; in incomplete dominance, heterozygotes have an intermediate phenotype.e. In codominance, all genes are recessive; in incomplete dominance, one gene is recessive to two dominant genes

Answer:

The correct answer is option d. "In codominance, two alleles are expressed equally; in incomplete dominance, heterozygotes have an intermediate phenotype".

Explanation:

Codominance and incomplete dominance are two exception of the classic genetic rules described by Gregor Mendel, at which an allele is dominant and the other allele is recessive. In codominance, two alleles are expressed equally, therefore the phenotypes of both alleles are expressed in heterozygotes. On the other hand incomplete dominance, describes a relationship of alleles at which heterozygotes have an intermediate phenotype. For instance, an heterozygote for the allele of red flowers and the allele of white flowers, will express a pink flowers phenotype.

As they multiply die and decompose algae deplete the oceans surface layers of oxygen. often the large amounts of farm fertilizer that run from fields into the rivers cause algae populations to explode. the most likely result is that

Answers

The most likely result of such a condition would be the reduction in the number of animals, plants and fishes that could have survived in the water. The water would also become more acidic in nature and all living things will start dying. The water would also become unusable for the humans. This water will increase the pollution level in surrounding areas and deplete the quality of the soil.
