though some organism have same number of chrosomes the phenotype (outward characteristics )of an organism is decided by the both genotype and the environment in which decided the appearance of organism even in the presence of an alternative gene is know as a dominate gege .it dominated the recessive gene for the same characteristics on other chrosomes of the pair.

Answer 2

Answer:

The characteristics of a species such as physical appearance, body functions and behavior are not only the outcome of chromosome number, but these depend on the genotype of every organism. That means the set of genes present in the organisms may vary and therefore lion, tiger and domestic cat have the same number of 38 chromosomes, their characteristics (like different appearances) are the result of the genes located on the chromosomes.
