Haploid After is complete the resulting gametes are haploid

Haploid. After is complete, the resulting gametes are haploid. This means there is 1 homolog present for each homologous pair. \"Keep in mind that, for better or for worse, we tend to focus largely on diploid organisms, like ourselves and fruit flies, in many biology courses. Not all organisms are diploid. The strawberries you buy at a grocery store are, for example, actually octaploids (8n). SIMULATING CELL DIVISION MEIOSIS WITHOUTRECOMBINATION Using the same 4 chromosomes you put together for the mitosis simulation, start with 4 unreplicated 4 chromosomes at G1 of interphase and simulate the events of meiosis. Beginning with the meiocyte, write out the chromosome numbers, just as you did for mitosis. G2: As you move the chromosomes through each phase of cell division in meiosis, describe to your lab partner all of the events that occur. Write out the chromosome numbers for each phase below.

Solution

G1: 4 unreplicated chromosomes (i.e, singlet chromosomes)

S: 4 replicated chromosomes (i.e, doublet chromosomes)

G2: 4 replicated chromosomes (i.e, doublet chromosomes)

Prophase I : 4 replicated chromosomes (i.e, doublet chromosomes)

Metaphase I :4 replicated chromosomes (i.e, doublet chromosomes)

Anaphase I : 4 replicated chromosomes (i.e, doublet chromosomes) they are being separated at this stage. 2 replicated chromosomes move towards one end and other 2 replicated towards opposite end.

Telophase I : 2 replicated chromosomes in each dividing cell.

Interkinesis: 2 daughter cells are formed each consisting 2 replicated chromosomes.

Prophase II : 2 replicated chromosomes in each of the two daughter cells.

Metaphase II : 2 replicated chromosomes in each daughter cell arranged on metaphasic plate.

Anaphase II : 2 singlet chromosomes would move toward one end of each daughter cell, other 2 singlet chromosomes towards the opposite end.

Telophase II : 2 singlet chromosomes in each of the 4 dividing cells.

cytokinesis: each of the 4 daughter cells would contain 2 singlet chromosomes.
