Why offsprings differ from parents in certain characters?

Text Solution

Verified by Experts

It is due to biparental percentage. The genes on chromosomes which pass over to the next generation is partly derived from both the parents (mother and father). During fertilisation of egg by the sperm, new combination of chromosomes enter the zygote, due to which certain variations occur in the offsprings. Thus, brothers and sisters show variations in their complexion, habits and behaviour .

    Why are offspring of oviparous animals at a greater risk as compared to offspring of viviparous animals?

    The new individual shows similarities with the parents for some characters and has some characters different than both parents .Justify the statement.

    If the majority of offsprings exhibit a dominant character, then the parents must be:
