Biology

Sladkaya [172]4 years ago
4 0

Dominant traits are those that are expressed or seen when a heterozygous genotype is present. Heterozygous just means having two different alleles for a gene. One is usually dominant while one is recessive. Remember, recessive alleles are masked by dominant alleles. In humans, dark hair is a dominant trait; if one parent contributes a gene for dark hair and the other contributes a gene for light hair, the child will have dark hair.

Mitosis is a type of cell division in which the cell divides its replicated chromosome in equal amount in two daughter cells. Mitosis takes place in four phases: Prophase, Metaphase, Anaphase and Telophase.

Metaphase is the stage of the cell division during which the chromosome is present in the highly condensed form present in the centre of the cell. The chromosomes are aligned at the equator of the cell.
