Question

Complete the table below by filling in the spaces with the correct stage of meiosis—Beginning, Meiosis I, Meiosis II, End. Event Stage in MeiosisThe double-stranded chromosomes move to thecenter of the cell. The centromeres separate. 1Two cells form, each with half the number ofchromosomes. Each chromosome still has twochromatids. 2Four sex cells form with half the number ofchromosomes as the parental cells. 3The chromosomes are copied. 4A. What is the chromosome theory of inheritance?B. Why is it important that sex cells have half the number of chromosomesas body cells?C. The process by which the number of chromosomes is reduced by half toform sex cells is called ________.

Answer 1

1. Meiosis 1.

2. Meiosis 2.

3. End.

4A. The chromosome theory of inheritance states that chromosomes are the main carriers of the genetic factors responsible for inheritance.

B. Body cells have two sets of chromosomes while sex cells have one set. Therefore, when two sex cells meet, they form an embryo with two copies of each chromosomes thereby producing a body cell with the exact number of chromosomes. In essence, meiosis maintains the right number of chromosomes of body cells by creating half the number of chromosomes of sex cells.

C. Meiosis.
