Question

Among lion ,tiger and domestic cat ,all the three have the same number of 38 chromosomes ,yet they have different appearances.how do you account for such differences?

Answer 1

Phenotype or external appearance does not depend on the number of chromosomes instead it depends on the genotype or genetic make up of the organism

Answer 2

The trait of an organism is determined the genes present on the chromosome and not the chromosome number.

Explanation:

• Chromosome number refers to the number of chromosomes present in the organism.
• The trait or a character is determined by the genes or the nucleotide sequence present on the gene, which is present on a highly packaged structure of DNA called the chromosome.
• If the variety of the same traits observed in the organism like in the case of the cats, lion, and tigers then it is the result of the variation in the genes of these organisms and not the chromosome numbers.  

Thus, these organisms have different variations for the same trait.
