Question

Dog and chicken both have same number of chrosoms,78.Yet they have different appearance.How do you account for such difference?​

Answer 1

Answer:

because it has different genes

Answer 2

Dog and chicken both have the same number of chromosomes,78. Yet they have a different appearance, because of the following reasons:-

• Rather than having the same number of chromosomes, dogs and chickens have different appearances because the genetic makeup of every individual is different.
• Also, the phenotype of any organism is not determined by the number of chromosomes but by the genotype of the organism.
• In any organism, around 50% of genes are still undiscovered.
• Of the rest 50%, only 2% of the genes code for the protein, and the rest part of the DNA does not have any specific function to perform.
• In the case of humans, around 99.9% of the DNA is the same for everyone and the difference comes in 0.1% which makes us different from each other.
• So, it is the genetic makeup of any individual which decides how an organism will going to look, rather than the number of chromosomes.

Hence, dogs and chickens both have the same number of chromosomes,78. Yet they have different appearances.
