Answer 2

Explanation:

Cytology has made an important contribution to taxonomy during last few decades. ..

♒Cytotaxonomy is the branch of biology dealing with the relationships ... Improvement in the cytological techniques permit chromosomal studies .

♒Chromosome numbers are mainly determined at mitosis and quoted as the diploid number (2n). Another important taxonomic character is the position of the centromere.

♒Meiotic behaviour sometimes shows the heterozygosity of inversions. Cytological data is significant than other taxonomic evidence.

♒.The Study of primate chromosome is another very active field,which provide very much information on relationships(chiarelli,1996). The number, structure, and behaviour of chromosomes is of great value intaxonomy, with chromosome numberbeing the most widely used and quoted character.

♒Chromosome numbers are usually determined at mitosis and quoted as the diploid number (2n), unless dealing with a polyploid series in which case the base number or number of chromosomes in the genome of the original haploid is quoted.
