Answer:
As a tiger grows his genes change
Explanation:
Development from a fertilized egg to a mature organism depends on the expression of different genes at different times. In addition, gene expression can occur in different parts of the body at different times during development. As the fertilized egg begins to divide, different genes are either turned on or off. The activation of specific genes is the most important step in cell differentiation. As the tiger grows and develops, different genes are either turned on or off in the tiger’s various cells. This regulation is a key part of development and differentiation.
