Question

Why do you not exactly resemble your parents? Give two reasons why.

Answer 1

Genetic information is inherited to the offspring by gene, which are the storage unit of this information. they are located inside the chromosome and they occupy specific position . the number of chromosome is constant inside species but, different between other species. In human the number of chromosome is 46. here, 44 are autosomal I.e..not a sex chromosome and remain 2 chromosome are sex  chromosome. each set have same characteristics respect the other set and one come from our mother by ovum and other are come from father by sperm . by crossing the inheritance character are developed. 50% character from mother and 50% character by father. therefore, in offspring not exactly look like a parents.

environment = environment is also responsible for character of offspring . location, and temperature provide the different character to the offspring.
