Answer:
Genetic variation is caused by:
mutation
random mating between organisms
random fertilization
crossing over (or recombination) between
chromatids of homologous chromosomes during
meiosis
Answer:
One type of cell that is similar to parent cell.
Explanation:
The cells undergo cell division either by mitosis and meiosis. The meiosis produces four genetically dissimilar daughter cells as the process undergoes recombination event which exchanges the genetic sequence.
The process of recombination does not take place in the mitotic division and also the daughter cell exhibit the same number of chromosome.
In the given question, since the cell with the genotype Aa Bb Cc undergo mitotic division, therefore, the daughter cell will be produced with the same genetic material and no genetically different cells.
Thus, One type of cell that is similar to parent cell is correct.
