Answer to Question #118937 in Evolution for NIBEDITA RUDRA

Question

Chromosome number is of no use in a key.Is it true or false? Give reason for your answer.

Answer 1

True.

Chromosomes are important because they contain directions for how cells will operate. For instance, the X- and Y-chromosomes tell an embryonic cell whether the organism will be male or female.

Chromosomes are very important and we cannot do without them this is because they are carriers of genes. They are also important in the exchange of genetic material before they are made into new a 'new individual'. 

They are very important in duplication of deoxyribonucleic acid (DNA) which replicates itself and protects it.
