WebDrosophila has four pairs of chromosomes (Fig. 8.3). Each linkage group in Drosophila was associated with one pair of chromosomes and the linkage groups were numbered 1, 2, 3 and 4. Further, the number of genes in each linkage group was found to be proportional to the size of chromosomes. Thus, the tiniest dot-like chromosomes are found to ... address of equifax canada WebWh do we use Drosophila for Culture? Easy to grow in lab.

A diploid organism has two copies of each chromosome. If it has four chromosomes, there are two pairs, A and A’ and B and B’, not four different chromosomes A, B, C and D. One copy of each chromosome came from its father (e.g. A and B) and one copy of each came from its mother (e.g. A’ and B’). address of equity residential WebDec 11, 2024 · The total number of linkage groups in an organism corresponds to the haploid number of chromosomes, i.e., to the number of chromosome pairs. In Drosophila, 2n = 8; n = 4. This means that the haploid number of chromosomes in Drosophila is 4. Therefore, there are 4 linkage groups in Drosophila.
