Biology

The chart below refers to meiosis in a diploidindividual composed of cells with 10 chromosomes during the G1phase.  Fill in the missing meiotic stage, description ofmajor event during that stage, or # of chromosomes/# of DNAmolecules.

Phase of Meiosis

Description of major event

# of chromosomes/# of DNA molecules

Replicated chromosomes align midway between spindle poles

5 chromosomes / 10 DNA molecules

Earliest stage of meiosis at which homologous chromosomes arepaired

Immediately following Telophase I

Anaphase I

10 chromosomes / 10 DNA molecules

Metaphase I

Replicated chromosomes re-condense after reductive division

So that chart starts out by saying that a cell has 10chromosomes in G1 phase of the cell cycle. Remember that G1precedes meiosis I. Saying that the cell has 10 chromosomes in G1is saying that the diploid number of chromosomes in 10. Another wayto say it is that there are 5 homologous pairs ofchromosomes.   

So 5 is the haploid number. The point of meiosis is to makehaploid gametes (sperm or egg cells). And the transition fromdiploid to haploid comes as the cell completes telophase I. Socells are diploid throughout meiosis I; then they are haploidthroughout meiosis II.

The goal of meiosis II is to convert a haploid number ofreplicated chromosomes into a haploid number of unreplicatedchromosomes (this involves the separation of sister chromatids inanaphase II).
