An organism's sex is defined by the gametes it produces: males produce male gametes (spermatozoa, or sperm) while females produce female gametes (ova, or egg cells); individual organisms which produce both male and female gametes are termed hermaphroditic. Frequently, physical differences are associated with the different sexes of an organism; these sexual dimorphisms can reflect the different reproductive pressures the sexes experience.
Sex in animals involves the fusion of a sperm and an egg cell.

In biology, sex is a process of combining and mixing genetic traits, often resulting in the specialization of organisms into male and female types (or sexes). Sexual reproduction involves combining specialized cells (gametes) to form offspring that inherit traits from both parents. Gametes can be identical in form and function (known as isogametes), but in many cases an asymmetry has evolved such that two sex-specific types of gametes (heterogametes) exist: male gametes are small, motile, and optimized to transport their genetic information over a distance, while female gametes are large, non-motile and contain the nutrients necessary for the early development of the young organism.

Facts

The plaintiffs, Mildred Loving (nee Mildred Delores Jeter, a woman of African and Rappahannock Native American descent, 1939 – May 2, 2008)[2][3] and Richard Perry Loving (a white man, October 29, 1933 – June 1975), were residents of the Commonwealth of Virginia who had been married in June 1958 in the District of Columbia, having left Virginia to evade the Racial Integrity Act, a state law banning marriages between any white person and any non-white person.

Upon their return to Caroline County, Virginia, they were charged with violation of the ban. They were caught sleeping in their bed by a group of police officers who had invaded their home in the hopes of finding them in the act of sex (another crime). In their defense, Ms. Loving had pointed to a marriage certificate on the wall in their bedroom. That, instead of defending them, became the evidence the police needed for a criminal charge since it showed they had been married in another state. Specifically, they were charged under Section 20-58 of the Virginia Code, which prohibited interracial couples from being married out of state and then returning to Virginia, and Section 20-59, which classified "miscegenation" as a felony punishable by a prison sentence of between one and five years.

On January 6, 1959, the Lovings pleaded guilty and were sentenced to one year in prison, with the sentence suspended for 25 years on condition that the couple leave the state of Virginia. The trial judge in the case, Leon Bazile, echoing Johann Friedrich Blumenbach's 18th-century interpretation of race, proclaimed that

Sexual reproduction

The life cycle of sexually reproducing organisms cycles through haploid and diploid stages.

Sexual reproduction is a process where organisms form offspring that combine genetic traits from both parents. Chromosomes are passed on from one parent to another in this process. Each cell has half the chromosomes of the mother and half of the father's.[1] Genetic traits are contained within the dioxyribonucleic acid (DNA) of chromosomes — by combining one of each type of chromosomes from each parent, an organism is formed containing a doubled set of chromosomes. This double-chromosome stage is called "diploid", while the single chromosome stage is "haploid". Diploid organisms can, in turn, form haploid cells (gametes) that randomly contain one of each of the chromosome pairs, via a process called meiosis.[2] Meiosis also involves a stage of chromosomal crossover, in which regions of DNA are exchanged between matched types of chromosomes to form a new pair of mixed chromosomes. Crossing over and fertilization (the recombining of single sets of chromosomes to make a new diploid) result in the new organism containing a different set of genetic traits from either parent.

In many organisms the haploid stage has been reduced to just gametes specialized to recombine and form a new diploid organism; in others, the gametes are capable of undergoing cell division to produce multicellular haploid organisms. In either case, gametes may be externally similar, particularly in size (isogamy), or may have evolved an asymmetry such that the gametes are different in size and other aspects (anisogamy).










By convention, the larger gamete (called an ovum, or egg cell) is considered female, while the smaller gamete (called a spermatozoon, or sperm cell) is considered male. An individual that produces exclusively large gametes is female, and one that produces exclusively small gametes is male. An individual that produces both types of gametes is a hermaphrodite; in some cases hermaphrodites are able to self-fertilize and produce offspring on their own, without a second organism.
