Which of the following statements is correct about variation?

Offsprings are different from their parents only

Offsprings from the same parents look alike

Offsprings differ from their ancestors but look like their immediate parents

offsprings differ from their ancestors and from each other Correct answer

Answer Details

The correct statement about variation is that "offsprings differ from their ancestors and from each other". This means that due to the process of genetic recombination and mutation, offspring inherit a unique combination of genes from their parents, which can result in differences between siblings and differences from their ancestors. While siblings may share some similarities due to inheriting some of the same genes from their parents, they are not identical and will exhibit variations in traits such as height, eye color, and hair color. These variations allow for diversity within a species and can be important for adaptation to changing environments.
