choose the best explanation of codominance.
a. genes are blended during homologous recombination.
b. in a heterozygote, both alleles are expressed.
c. in a heterozygote, both alleles combine to form an intermediate phenotype.
d. a heterozygote is considered a carrier for the recessive allele.

In a heterozygote, both alleles are expressed. - is the best explanation of codominance.

Explanation:

Closely related to incomplete dominance is codominance, in which both alleles are simultaneously expressed in the heterozygote. Codominance is a relationship between two versions of a gene. Individuals receive one version of a gene, called an allele, from each parent. If the alleles are different, the dominant allele usually will be expressed, while the effect of the other allele, called recessive, is masked.

prokaryotic cells do not have a nucleus in which the dna is stored in, it floats freely inside the cell.

eukaryote cells do have a nucleus in which the dna is stored in.

hi~~

i would say that hybridization occurs frequently in nature, because there are many types of hybrids that have occurred naturally, such as the mule (male donkey + female horse)
