the female reproductive cell

capacitation

Occurring in the female reproductive tract, _____ is the process by which spermatozoa become capable of fertilizing an egg.

vas deferens

a duct that carries spermatozoa from the epididymis to the ejaculatory duct

ejaculatory duct

Tube through which semen enters the male urethra

gamettes

reproductive cells

diploid

(genetics) an organism or cell having two sets of chromosomes or twice the haploid number

haploid

(genetics) an organism or cell having only one complete set of chromosomes

what is the objective of meiosis

result in reduction in chromosome numbers to half result of meiosis is 4 daughter cells

what is the importance of the haploid number

instead of having two sets of chromosomes you have one set
