Answer 1

Difference between sperms and eggs of humans:-

The major genetic differences lies in the difference in sex chromosome of sperm (male gamete) and egg( female gamete). Sperm has Y chromosome as sex chromosome, while egg has X chromosome as sex chromosome. There is a marked difference in  size, shape, metabolic activity, cytoplasm content, motility, etc in the sperms and eggs.
Human eggs are much larger than sperms and are highly metabolically active cells. They contain more amount of cytoplasm.
