During sexual reproduction, a femalegamete (having 23 chromosomes) fuses with a male gamete (having 23 chromosomes) to form zygote. Zygote is diploid which contains 23 chromosomes from mother and 23 from father. In this way, an equal genetic contribution of male and female parents is ensured in the progeny.

How is the equal genetic contribution of male and female parents ensured in the progeny?
During the formation of gametes as a result of reductional division (meiosis), sperms - XY & eggs - XX receive only single genome of a parent.
When fertilization occurs, one genome each from sperm & egg reaches the zygote.
It means both male & female parents contribute exactly equal amount of genetic material to the offspring.
