What factor governs family resemblances in families?
- Meiosis I and II are responsible for replication of homologous chromosomes.
- Mitosis always works with homologous chromosomes, which are multiplied.
- Meiosis works with homologous chromosomes, which are from both parents.
- Meiosis picks one homolog, thus choosing one parent's traits over the other parent's.
You resemble your family members because you are a product of your parents who are products of their grandparents. Therefore the type of cell division that works with chromosomes from both of your parents governs family resemblances.

Which statement below best describes meiosis?
- Homologous pairs of chromosomes in a haploid cell are duplicated, and the copies are sorted into two different haploid daughter cells.
- Homologous pairs of chromosomes in a diploid cell are replicated, and the copies are sorted into four different haploid daughter cells.
- Homologous pairs of chromosomes in a diploid cell are duplicated, and the copies are sorted into two different haploid daughter cells.
- Homologous pairs of chromosomes in a haploid cell are replicated, and the copies are sorted into four different diploid daughter cells.
Meiosis is basically reduction division. During the process of meiosis, the chromosomal number is reduced and the number of daughter cells increases.

Why is meiosis I called reductional division?
- When homologous chromosomes duplicate, they separate into two sister chromatids.
- When homologous chromosomes replicate, they form haploid cells.
- When homologous chromosomes separate, the diploid cells became haploid cells.
- Homologous chromosomes reduce the number of chromosome sets in haploid cells.

What happens during the crossover event in meiosis?
- Fragments of adjacent non-sister chromatids exchange chromatid material.
- Portions of non-adjacent sister chromatids exchange chromatid material.
- Segments of adjacent non-sister chromatids exchange chromatid material.
- Segments of non-adjacent sister chromatids exchange chromatid material.
Homologous chromosomes that have duplicated line up side by side. A sister chromatid from a duplicated homologous chromosome can swap chromatid materials with a sister chromatid from an adjacent duplicated homologous chromosome.

Sister chromatids undergo this change in meiosis II. This is a type of equational division very similar to mitosis. What happens to sister chromatids in meiosis II?
- Separation and assortment of sister chromatids results in diploid daughter cells.
- Synapsis of sister chromatids using a zipper protein results in haploid daughter cells.
- Movement of the sister chromatids results in the production of diploid daughter cells.
- Separation of the sister chromatids results in the production of haploid daughter cells.
Every haploid daughter cell of the four haploid daughter cells that are produced at the end of meiosis must contain one chromosome that was once a part of a pair of sister chromatids.
Every haploid daughter cell of the four haploid daughter cells that are produced at the end of meiosis must contain one chromosome that was once a part of a pair of sister chromatids.

What mechanism in meiosis contributes to the genetic difference between parents and children?
- arrangment in metaphase II
- synapsis of chromosomes
- crossing over in prophase I
- detachment in telophase II
