Meiosis
| Term | Definition |
|---|---|
| gametic cells/ gametes | sex cells-sperm and egg OR pollen and ovule |
| fertilization | involves two parents to produce a zygote. Example in animal reproduction is fusion of sperm and egg |
| homologous chromosomes | paired chromosomes containing the same trait with different variations |
| crossing over | parts of homologous chromosomes exchange information and leads to genetic variation (diversity) |
| diploid | 2 sets of chromosomes represented by 2N found in somatic cells |
| haploid | 1 set of chromosomes represented by 1N or N found in gamete cells |
| somatic cells | body cells |
| meiosis | process of reduction division in which the chromosome number is cut in half through 2 cell divisions |
| Result of Meiosis | 4 genetically different haploid cells |
| independent assortment | chromosomes are sorted randomly into daughter cells creating new combinations |
| zygote | a fertilized egg, contains a full set of chromosomes (2n) |
