After mitosis, two identical diploid cells are formed. In the exposed example, each cell has a chromosome with the L allele and another chromosome carrying the l allele.
Mitosis is a process by which, from a diploid somatic cell (2n), two daughter diploid cells (2n) are produced.
First occurs duplication of the cell content, and then the separation into two new cells happens.
Mitosis occurs in only one phase.
• In the prophase, it occurs chromosomes condensation and nuclear membrane breaks.
• During the metaphase, chromosomes are taken toward the center of the cell by the spindle apparatus. Once in the equatorial plane, chromosomes line up.
Each chromatid joins with a microtubule of opposites poles.
• In Anaphase, chromatid sisters separate. The bonds that were keeping them together break, and each of them migrate to the opposite poles.
• In telophase, duplicated chromosomes are already in the corresponding poles, and the nuclear membrane forms again in each pole.
• Finally, cytokinesis occurs.
In the exposed example, considering<u> only </u>the chrosomomes carrying the L and l alleles, each daughter cell ends with two homologous chromosomes,
- one of them with the recessive allele
- the other one with the dominant allele
