Bond [772]

Answer:

At the end of mitosis, __two________ daughter cells that are genetically _____similar_____ are formed, while at the end of meiosis, _____four_____ daughter cells that are genetically _____distinct_____ are formed.

Explanation:there are two types of cell division; mitosis which occurs in somatic cells and meiosis which occurs in reproductive cells.

In mitosis, division occurs once leading to the production of two daughters cells.crossing over does not occur in the chromosome, so the daughter cells are genetically identical to the parent cell.

In meiosis,cell division occurs twice ,(meiosis I & II),leading to the production of four daughter cells.

Crossing over occurs,leading to genetic variation in the daughter cells.
