Oogenesis production or development of an ovum
Ovum/ova mature female reproductive cell
Sperm male reproductive cell
Zygote fertilized egg
Tetrad set of 4
Synapsis fusion of chromosome pairs at the start of meiosis
Fertilization two gametes fuse to become a zygote
Disjunction homologous chromosomes move apart toward the opposite poles of the cell in anaphase I and sister chromatids separate and move away from each other during anaphase II
Gametogenesis cells undergo meiosis to form gametes
Homologous chromosome chromosome pairs that are similar in length, gene position, and centromere location
Crossing over the exchange of genes between homologous chromosomes, resulting in a mixture of parental characteristics in offspring
Gonads reproductive organs
Spermatogenesis the production or development of mature spermatozoa.
Polar Bodies each of the small cells which bud off from an oocyte at the two meiotic divisions and do not develop into ova
Meiosis a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores.
Variation a different or distinct form or version of something.
Nondisjunction failure of one or more pairs of homologous chromosomes or sister chromatids to separate normally during nuclear division
