How many chromosomes would the sex cells of an organism with #12# chromosomes have?
2 Answers
See below.
Explanation:
Is it 12 pairs of chromosomes or just 12 chromosomes.
If it is 12 pairs, the sex cells (or gametes) will have half the number of pairs of chromosomes i.e. 6 pairs.
If it is just 12 chromosomes, which is 6 pairs, the gametes will have half of the 6 pairs i.e. 3 pairs.
Hope this helps :)
Sex cells will have 6 chromosomes.
Explanation:
The diploid organism has all chromosomes in pairs, one chromosome inherited from male parent & another chromosome in the pair is inherited from the female parent.
If an organism has 12 chromosomes, it has 6 different types of chromosomes, differing from one another in length, the position of centromeres and genes present on these.
Six different types of chromosomes constitute a haploid set of chromosomes. Two chromosomes of the same type are called homologous chromosomes and these constitute a homologous pair.
The cells producing sex cells or gametes undergo meiosis (reduction division) so that each gamete contains only one chromosome of a homologous pair.
The gametes are haploid, having half the number of cells as compared to somatic cells.
The gametes or sex cells produced by the organism will have 6 chromosomes if the organism has 12 chromosomes.
