Afemale blue jay is generating an egg cell for reproduction.
through which process does the egg cell form?
(1) meiosis.
(2) prophase.
(3) fertilization.
(4) mitosis.

The answer is: 1. Meiosis

During the meiosis process,  one cell of the female blue jay would be divided two times and formed four cells. These four cells that's just formed only have half amount of the chromosomes from the original cells, and this is the one that is used in reproduction. Because of this half chromosomes, children would had the combination of characteristics from both parents.

sounds good to me mate!
