blueprint of life diploids (1 Viewer)

i have to make a model showing stages of meiosis
involving crossing over in one pair of chromosomes that results in haploid gametes
the model is based on a mosquito with a diploid number of 6

what does a diploid number of 6 mean ?

how can i show this in my model?

help!!!!!!!!!!!

Just that as a background, a haploid cell is found in sex cells only and there is only one of each chromosome (not pairs as in diploids) and is also known as (n).

Diploid is found in any other cells besides the sex cells and are pairs of homologous chromosomes (2n).

So if it is a diploid number of 6, it will mean 6 = 2n.

The resulting haploid gametes will have 3 chromosomes. You can look at your textbook for images of how meiosis occurs and follow this table. Remember that crossing-over in meiosis occurs when the chromosomes line up during Metaphase (first stage of division).
