HSC 2100 Lecture Notes - Lecture 51: Artificial Insemination, Asexual Reproduction, Genetic Engineering
Document Summary
Male part of the flower where sperm (pollen) are produced by meiosis. The tip of the female reproductive structure of a flower where the pollen lands. Artificially controlled reproduction, as female organisms are inseminated based on human selection for breeding of ideal traits. Eg, artificial insemination of ideal bull"s sperm into female calfs to encourage meat quality, milk. This can increase genetic diversity in the short term, as new favourable traits may be introduced from other populations or enhanced through selective breeding. However in the long term, there will be a decrease in the genetic diversity of the population as similar preferable attributes are selected for the entire population. Genetic engineering in which an identical copy of gene or an entire organism is produced. Significant and immeadiate decrease in genetic diversity. Dna from bt bacteria inserted into plant crops. Cotton crops become resistant to certain insects.
