The separation of the sister chromatids during the cell division occurs in the anaphase in mitosis and anaphase II in meiosis.
During the anaphase in mitosis, and the anaphase II of the meiosis, the chromosomes aligned at the center of the nucleus separates and the sister chromatids of the chromosomes starts moving towards the opposite poles as the spindle fibers starts contracting.
False , as with deer , a buck has antlers , and a doe has no antlers
Answer:
The most common interaction between alleles is a dominant/recessive relationship. An allele of a gene is said to be dominant when it effectively overrules the other (recessive) allele. Eye colour and blood groups are both examples of dominant/recessive gene relationships.
The main difference between dominant and recessive trait is that dominant genes always passes the dominant behavior genes while the recessive ones pass the recessive behavior genes. In fact, the dominant genes are said to be more likely to pass to future generations, while the recessive ones are less likely to do that.
Explanation:
C the appearance of new phenotypes in the offspring
Answer:
