Variation
Diploid
The male gamete or ’sperm’, and the female gamete, ’egg’ or ’ovum’ are specialized sex cells, which fuse together to begin the formation of a zygote during a process called sexual reproduction
Different forms of something
The failure of homologous chromosomes or sister chromatids to separate properly during meiosis
A cell that contains pairs of homologous chromosomes (2n)
A cell that contains single set of chromosomes (n)
Cell division that results in haploid gametes cells
The exchange of genetic material between homologous chromosomes during prophase I in meiosis. Contributes to genetic variation
Cells that contain half the total number of chromosomes for an organisms; sex cells
Different forms of the same gene such as flower color or eye color
A diploid cell resulting from the fusion of the sperm and egg
A set of one maternal and one paternal chromosome similar in size that pair up with each other inside a cell during meiosis; each carries the same gene
