What process in meiosis makes daughter cells genetically different?
Meiosis also produces genetic variation by way of the process of recombination. Later, this variation is increased even further when two gametes unite during fertilization, thereby creating offspring with unique combinations of DNA.
How the processes of meiosis result to variation of genes and genetic disorders?
During meiosis, homologous chromosomes (1 from each parent) pair along their lengths. The chromosomes cross over at points called chiasma. At each chiasma, the chromosomes break and rejoin, trading some of their genes. This recombination results in genetic variation.
Is there genetically different between parent and daughter cells produced by mitosis?
Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies – or ‘replicates’ – its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.
What is the difference between daughter cells and parent cells?
In mitosis, the daughter cells have the same number of chromosomes as the parent cell, while in meiosis, the daughter cells have half the number of chromosomes as the parent.
What happens to daughter cells after meiosis?
By the end of meiosis, the resulting reproductive cells, or gametes, each have 23 genetically unique chromosomes. The overall process of meiosis produces four daughter cells from one single parent cell. Each daughter cell is haploid, because it has half the number of chromosomes as the original parent cell.
Are human body cells haploid?
Haploid describes a cell that contains a single set of chromosomes. In humans, gametes are haploid cells that contain 23 chromosomes, each of which a one of a chromosome pair that exists in diplod cells. The number of chromosomes in a single set is represented as n, which is also called the haploid number.
