NEET BIOLOGY

Detailed explanation-1: -When the offspring inherit different DNA from their parents, each offspring will have Heterozygous traits.

Detailed explanation-2: -Offspring that result from crosses between parents with different traits are called hybrids.

Detailed explanation-3: -Every child gets 50% of their genome from each parent, but it is always a different 50%. During meiosis, gametes get a random chromosome from each pair. This means that there are over 8 million possible DNA combinations from 23 chromosome sets!

Detailed explanation-4: -Genetic variations can arise from gene variants (also called mutations) or from a normal process in which genetic material is rearranged as a cell is getting ready to divide (known as genetic recombination). Genetic variations that alter gene activity or protein function can introduce different traits in an organism.

Detailed explanation-5: -Parents pass on traits or characteristics, such as eye colour and blood type, to their children through their genes. Some health conditions and diseases can be passed on genetically too. Sometimes, one characteristic has many different forms.
