An allele is dominant and heterzygote (Pp) when a dominant allele (P) is crossed with a recessive allele (p).
Explanation:
A dominant allele is the one with a particular dominant character or phenotype which dominates even though there are other alleles found.
A heterozygous allele results from two different alleles coding for a gene.
A heterozygous dominant allele (Pp) results from the crossing of a dominant allele (P) with a recessive allele due to complete masking of the recessive allele (p).
For example, when dominant brown eyes are crossed with recessive blue eyes, in a heterozygous dominant allele results in brown eyes and masks the recessive blue eyes.
The best answer is C
The process by which a cell divides is called mitosis. It results in two daughter cells that are genetically identical to each other and to the original cell.
Multicellular organisms, depend on mitosis for growth and repair. Organisms repair some of their tissues using mitosis to regenerate new cells. Not all cells undergo mitosis at the same rate. In man, brain cells are much more difficult to regenerate than cheek cells which are constantly being replaced.
Answer:
Symbiosis is an interaction characterized by two or more species living purposefully in direct contact with each other. The term "symbiosis" includes a broad range of species interactions but typically refers to three major types: mutualism, commensalism and parasitism.
