Well, yes, there is. The answer relates to the size of cells that will fuse together to produce the next generation (the sex cells or gametes). The individual that produces the relatively smaller gamete is universally called “male” and the individual that produces the relatively larger gamete “female”.
Do all the gametes?
Human females have the two X chromosomes called sex chromosomes as the 23rd pair of chromosomes. During meiosis at the time of gamete formation, one X chromosome enters each gamete. Hence all the female gametes possess an X chromosome.
Do males produce gametes?
They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome. … The ova mature in the ovaries of females, and the sperm develop in the testes of males.
Do males produce 4 gametes?
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.
Is a sperm a cell?
In the human reproductive process, two kinds of sex cells, or gametes (GAH-meetz), are involved. The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female’s reproductive system.
Do gametes determine gender?
Sperm cells carry either an X or Y sex chromosome. Female gametes, or eggs, however, contain only the X sex chromosome and are homogametic. The sperm cell determines the sex of an individual in this case. If a sperm cell containing an X chromosome fertilizes an egg, the resulting zygote will be XX, or female.
Are gametes living?
Paulson points out, both the sperm cell and egg cell are living cells, as is the zygote formed from the fusion of the sperm and the egg.
Do all gametes have the same DNA?
Gametes contain half as many chromosomes as the other cells in the organism, and each gamete is genetically unique because the DNA of the parent cell is shuffled before the cell divides. This helps ensure that the new organisms formed as a result of sexual reproduction are also unique.
Do females produce more gametes than males?
Females generally produce a few but large gametes, whereas males produce large numbers of much smaller gametes. … Consequently, the limited number of gametes and the greater parental investment of the females result in an asymmetry in the degree of sexual selection between the two sexes.
