NEET BIOLOGY

Detailed explanation-1: -Eye colour So, if you have one allele for brown eyes and one allele for blue eyes (Bb), your eyes will be brown. (This is also the case if you have two alleles for brown eyes, BB.) However, if both alleles are for the recessive trait (in this case, blue eyes, bb) you will inherit blue eyes.

Detailed explanation-2: -Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents.

Detailed explanation-3: -If one parent has brown eyes and one has blue, the child could have either one. If the parent with brown eyes has brown-eyed parents, the child will likely have brown. However, if the parent with brown eyes has a blue-eyed parent, you could have a blue-eyed baby.

Detailed explanation-4: -For example, the allele for brown eyes is dominant, therefore you only need one copy of the ‘brown eye’ allele to have brown eyes (although, with two copies you will still have brown eyes).
