Document Summary
Germ cells, homologues, alleles, chaisma, chromatids, synapsis, crossing over, Asexual reproduction versus sexual reproduction as ex ual reproduc tion produces genetically identical copies of the parent. S ex ual reproduc tion involves the formation of sex cells (gametes), fertilization (fusion of gametes) and formation of zygote. Somatic cells versus germ cells s om atic c ells do not play a direct role in reproduction. Skin, blood, liver, muscle cells g erm c ells are set aside for the function of reproduction. Cells of ovary in females produce eggs, testes in males produce sperms these are the g am etes or s ex c ells that play a role in reproduction. The two chromosomes that make up a matched pair in a diploid of an organism. One chromosome of this pair is inherited from the father, the other from the mother. Homologous chromosomes are of the same length, centromere position, and possess the same genes or alternative form of a gene.
