Heyy❤ what is a gamete??
Answers
a male or female cell that joins with a cell of the opposite sex to form a zygote
HEY BUDDY❤
HERE IS YOUR ANSWER...
Gamete, sex, or reproductive, cell containing only one set of dissimilar chromosomes, or half the genetic material necessary to form a complete organism (i.e., haploid). Gametes are formed through meiosis (reduction division), in which a germ cell undergoes two fissions, resulting in the production of four gametes. During fertilization, male and female gametes fuse, producing a diploid (i.e., containing paired chromosomes) zygote.
Gametes may be identical in form (isogamy), as in certain species of algae, fungi, and protozoans, or there may be more than one morphological type (heterogamy, or anisogamy), as with many green algae of the genus Chlamydomonas. Gametes of animals, some algae and fungi, and all higher plants exhibit an advanced form of heterogamy called oogamy. In oogamy one of the gametes is small and motile (the sperm), and the other is large and nonmotile (the egg).
In addition, most species are also heterogametic – containing a different set of chromosomes in each type of gamete. In mammals, the female gamete contains a single X chromosome in addition to 22 somatic chromosomes. On the other hand, the male gamete, the sperm, could carry either an X or a Y chromosome as the 23rd chromosome. Depending on the chromosome present in the sperm, the resultant diploid zygote could either be a female (XX) or a male (XY). In birds, this form of heterogamy is reversed. Females produce gametes that could contain either the W or the Z chromosome and males produce a single type of gamete.
The two most common gametes are sperm and ova.
