Answer 1

1) Body cells are diploid and have two sets of chromosomes. Sex cells are haploid.

2) Steps of meiosis in order:
- matching chromosomes pair up and get ready to divide
- crossing-over trades genetic material between matching chromosomes
- matching chromosomes split into two new cells during meiosis I
- sister chromatids split apart to make four different haploid gametes during meiosis II

3) Meiosis makes haploid gametes that have only one set of chromosomes. This helps babies get the right chromosome number when fertilization happens.

4) Random assortment means chromosomes are sorted randomly into gametes. This makes each cell different every time meiosis happens.

5) Match each term with its meaning:
- Diploid — a cell that has two complete sets of chromosomes
- Haploid — a cell that has only one set of chromosomes
- Homologous chromosomes — matching chromosome pairs, one from each parent, that carry similar genes
- Gamete — a sex cell, like sperm or egg, that is haploid

6) Match each step with what happens:
- Crossing-Over — genetic material is traded between matching chromosomes to make new gene combinations
- Meiosis II — sister chromatids split apart, like normal cell division
- End of Meiosis — four different haploid gametes are made
- Meiosis I — matching chromosome pairs split into two new cells
