◉ most plants and animals produce_______.
Answer: gametes called eggs and sperm


◉ Meiosis.
Answer: nuclear division that forms haploid cells


◉ Meiosis I.
Answer: diploid cells divide to create 2 haploid cells, each with one
of the homologous chromosomes


◉ Meiosis II.

,Answer: 2 haploid cells divide to form 4 haploid cells, which develop
into eggs or sperm


◉ Prophase I (Meiosis).
Answer: -chromosomes condense
-nuclear envelope breaks down
