Meiosis Biology

All of the following result from Meiosis EXCEPT

• gametes are made

• the cells made have different genetic material

• the chromosome number reduces in half from the parent cell

• cells that are made are identical

All of the following are true about human gametes EXCEPT

• gametes are haploid

• an egg is an example of a gamete

• a zygote is an example of a gamete

• gametes contain NO chromosome pairs

What is the goal of Meiosis I ( the first division)

• add tails to the sperm

• create variety in the ending cells

• reduce the chromosome number in half from starting cell

• bring the pairs back together

What is the goal of Meiosis II (the second division)

• reduce the chromosome number in half from the starting cell

• separate the pairs

• create variety

• put a tail on the sperm

Diploid cells have pairs present. Which cell is NOT diploid

• somatic cell

• sperm

• zygote

• germ cell

What process converts a diploid cell (2n) into haploid (n) cells

• mitosis

• meiosis

• fertilization

During Meiosis, the cell is first haploid

• when the homologous pairs are copied

• by the end of meiosis 1, when the pairs separate

• by the end of meiosis II, when the sisters separate

• by the end of interphase when the spindle fibers attach

What process grows the zygote into a multi celled embryo?

• mitosis

• meiosis

• fertilization

Your genetics is 2n=46. What does the 46 mean?

• In each cell, there are 46 total chromosomes

• In your entire body, you have 46 chromosomes

• There are 46 pairs of chromosomes in each body cell

• The cell is 46 years old
