gamete | a reproductive cell |
synapsis | the pairing of homologous chromosomes during meiosis |
tetrad | a group of two homologous chromosomes during meiosis |
crossing-over | the exchange of genes by reciprocal segments of homologous chromosomes during meiosis |
genetic recombination | formation of new combinations of alleles in offspring (viruses, cells or organisms) as a result of exchange pf DNA sequences between molecules. It occurs naturally, as in sexual reproduction or experimentally, as a result of genetic engineering |
independent assortment | during meiosis, the random distribution of genes from different chromosomes to the gametes |
spermatogenesis | the production of sperm cells |
oogenesis | the production of mature egg cells |
polar body | one of two small cells produced ad discarded during each of the two meiotic divisions that yield the haploid egg |
asexual reproduction | the production of offspring that does not involve the union of gametes |
sexual reproduction | the production of offspring from the combination of genetic material from two parent organisms |
gamete | a reproductive cell |
synapsis | the pairing of homologous chromosomes during meiosis |
tetrad | a group of two homologous |
