Document Summary
Except for any mutations that occur during mitosis. Effect of sex on genetic variation in populations. New allele formation in a population is by mutation or integration. Reproducing sexually generates new multilocus combinations of alleles. Sexually reproducing species have offspring that are genetically different from the parent and each other (twins are exceptions) Half of genetic material comes from each parent. Sex is an important source of genetic variation. It"s possible to have reproduction without sex (asexual reproduction) It"s possible to have genetic exchange and create new combinations of alleles (aka sex) without reproduction coming into it. Donor bacterium transfers its genetic information to recipient. When there"s no option to reproduce sexually, organisms are called obligately asexual. When organisms have the option to produce both sexually and asexually, they"re called facultatively asexual. Send runners along the ground that grow offspring that are genetically identical. Use flowers that are pollinated to create seeds and then grow into new trees.
