Human offspring resemble their parents but are not identical to them due to fact that they get half of their DNA and inherited features from each parent and crossing over.
Humans reproduce by the process called sexual reproduction. Sexual reproduction involves the fusion of sperm and egg called fertilization that means they get their genetic material from mother and father equally.
Offsprings are genetically similar to offspring but not identical due to these factors:
- Offspring is produced by a combination of two different parent's gametes and each provides their genetic material to zygote.
- it generates variation in the offspring due to crossing over and fertilization
- These variations give them adaptable offspring as a survival advantage.
Thus, the correct answer is - they get half of their DNA and inherited features from each parent and crossing over.
