Question

Organism have different numbers of chromosomes. Fill in the chart below about 5 different organisms.

Please answer quickly, the work is due soon but our teacher as been absent for this whole unit.

Answer 1

• Number of chromosomes in haploid cells of humans = 23
• Number of homologous chromosome pairs in diploid cells of bat = 22 pairs
• Number of chromosomes in haploid cells of bat = 22
• Number of chromosomes in diploid cell of monkey = 42
• Number of chromosomes in haploid cells of monkey = 21
• Number of chromosomes in diploid cell of camel = 70
• Number of homologous chromosome chromosome pairs in diploid cells of camel = 35 pairs
• Number of homologous chromosome pairs in diploid cells of dog = 39 pairs
• Number of chromosomes in haploid cells of dog = 39

The diploid number represents the total chromosomes in a somatic cell, while the haploid number indicates the number of chromosomes in sex cells (gametes).

The number of homologous chromosome pairs is half of the diploid number and represents chromosomes with similar genes.

Thus, the haploid number and the number of homologous chromosome pairs of a cell are essentially the same and are equal to half the number of diploid.
