Question

crossing over genetic variation how many daughter cells are created at the end of meiosis 1? how many daughter cells are created at the end of meiosis 2? use the following word bank to answer the questions below. homologous independent assortment oogenesis polar bodies random assortment synapsis spermatogenesis tetrad what are pairs of matching chromosomes called? what is the pairing up of these chromosomes called? when they pair up containing 4 chromatids, what is this structure referred to? what term is given to the exchanging of genes of homologous chromosomes? what term is given to the chance distribution of chromosomes into daughter cells? the principle that genes are inherited completely and separately from each other. what term is given the meiotic process of making sperm cells? what term is given the meiotic process of making egg cells? during the process of female egg meiosis, 3 additional haploid cells that will not be fertilized are produced. what term is given those cells?

Explanation:

1. Pairs of matching chromosomes are called homologous chromosomes.
2. The pairing up of these chromosomes is called synapsis. When they pair up containing 4 chromatids, the structure is called a tetrad.
3. The principle that genes are inherited completely and separately from each other is the principle of independent assortment.
4. The process that leads to the unique distribution of chromosomes into daughter cells is called random assortment.
5. The term given to the exchanging of genes of homologous chromosomes is crossing - over.
6. The term given to the chance distribution of chromosomes into daughter cells is genetic variation.
7. The term given to the meiotic process of making sperm cells is spermatogenesis.
8. The term given to the meiotic process of making egg cells is oogenesis.
9. During the process of female egg meiosis, 3 additional haploid cells that will not be fertilized are called polar bodies.
10. At the end of meiosis 1, 2 daughter cells are created. At the end of meiosis 2, 4 daughter cells are created.

Answer:

1. Homologous chromosomes
2. Synapsis, Tetrad
3. Independent assortment
4. Random assortment
5. Crossing - over
6. Genetic variation
7. Spermatogenesis
8. Oogenesis
9. Polar bodies
10. 2 daughter cells at the end of meiosis 1; 4 daughter cells at the end of meiosis 2
