Which of the following statements is not true about chromosomes?
Answer Details
Homologous chromosomes do not occur in pairs naturally is not a true statement about chromosomes.
Homologous chromosomes are chromosome pairs (one from each parent) that are similar in size, shape, and carry the same genes but can have different alleles. They occur naturally in diploid cells, which have two sets of chromosomes, one from each parent.
The other statements are true about chromosomes. Each chromosome is made up of two chromatids that are held together by a centromere. Body cells have diploid numbers of chromosomes, meaning they have two sets of chromosomes. The sex cells have haploid number of chromosomes, meaning they have only one set of chromosomes. Finally, chromosomes have many transverse bands that help to distinguish one chromosome from another and aid in their identification.
