The answer is; C
Homologous chromosomes have the same genes on the same loci. However, they may have different forms of the same gene called alleles. These sister chromosomes, of a homologous pair, separate during anaphase I of meiosis. The two daughter cells formed will, therefore, have half the genetic material as the parent cell. This is because they will only have one set of the genes (as in diploid organisms) and are called gametes.
Answer:
<h2>Genotype, sequence, mRNA, cytoplasm, proteins, phenotype</h2>
Explanation:
The allele combination at a gene locus is known as an organism's genotype, which after expression define the phenotype of that organism.
Th sequence of nucleotide in the DNA then transcribed to produce mRNA by RNA polymerase. Then mRNA exported into the cytoplasm and works as template for the synthesis of protein. This protein defines the phenotype of that organism.
