Meiosis produces gametes that contain half the genetic information. Once the two gametes combine in fertilization the cell is now considered a zygote. This type of reproduction is called
Sexual
Asexual
Vegetative
During prophase I of meiosis the....
Nuclear envelope toughens
Homologous chromosomes cross over
Sister chromatids separate and move to opposite ends of the cell
Chromosomes become chromatin
Homologous pairs (homologs) are separated during anaphase II.
