Gametes are haploid reproductive cells produced during sexual reproduction. The fusion of a male gamete (sperm) with a female gamete (ovum) is called fertilization and gives rise to a diploid zygote. When a sperm enters the female genital tract, it migrates towards the ovum in the fallopian tube.

During the process of fertilization, a series of reactions triggers the fusion of gametes to produce a diploid cell called a zygote. …

Because the egg and sperm cells exist as a hemi-protoplast and as protoplasts in the embryo sac, respectively, to allow membrane fusion between gametes, it is possible that gamete fusion can occur around the chalazal surface of the egg cell, except for where it is attached to synergids (Fig. 1A).

Zygote is formed by the fusion of male and female gametes.

The zygote is formed by the fusion (or combining) of two gametes, i.e. male gamete and female gamete. This union of gametes resulting in a zygote is called fertilization.

The form of anisogamy that occurs in animals, including humans, is oogamy, where a large, non-motile egg (ovum) is fertilized by a small, motile sperm (spermatozoon).

My general response is that it’s a 50/50 chance that a woman will have a boy or a girl. But that’s not exactly true – there’s actually a slight bias toward male births. The ratio of male to female births, called the sex ratio, is about 105 to 100, according to the World Health Organization (WHO).

No. The mythological term “hermaphrodite” implies that a person is both fully male and fully female. This is a physiologic impossibility. The words “hermaphrodite” and “pseudo-hermaphrodite” are stigmatizing and misleading words.

Intersex people were categorized as either having “true hermaphroditism”, “female pseudohermaphroditism”, or “male pseudohermaphroditism”. These terms are no longer used, and terms including the word “hermaphrodite” are considered to be misleading, stigmatizing, and scientifically specious in reference to humans.
