Gamete
... " females " of the species produce the larger
gamete called an ovum (or egg) and " males " produce the smaller
gamete termed (in animals) a spermatozoon (or ... involved in the union. After fusion of the two
gamete nuclei , and after multiple cell divisions and ...
Genetic recombination

gamete contains a random assortment of chromatids, ... available. With recombination, however, the
gamete can receive a (mostly) random assortment of ... recombination, but severe problems can arise if a
gamete containing unbalanced recombinants becomes part ...
Meiosis

Cell growth
... diploid organisms. It produces four special daughter cells ( gametes ) which have half the normal cellular amount of DNA. A male and a female
gamete can then combine to produce a zygote , a cell which again has the normal amount of chromosomes.

gamete merge ( fertilization ), a new diploid organism is formed.

If the two alleles differ, then one, the dominant allele, is fully expressed in the organism's appearance; the other, the segregate during
gamete production. This is the last part of Mendel's generalization. The two alleles of the organism are separated into different gametes, ensuring ...

A sperm cell , or spermatozoon ( pl. spermatozoa ) (in Greek : sperm = semen and zoon = alive), is the haploid cell that is the male
