Anther
Male part of the flower where sperm (pollen) are produced by meiosis
Stigma
The tip of the female reproductive structure of a flower where the pollen lands
Artificial semination
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
PRODUCTION etc
Genetic diversity
- 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
Cloning
Genetic engineering in which an identical copy of gene or an entire organism is produced
- Asexual reproduction
METHODOLOGY EXAMPLE -Nucleus transfer
The transfer of genetic material from the nucleus of a donor adult cell to an egg cell that has had its
nucleus removed for the purpose of creating an embryo that can produce an exact genetic copy of the
donor organism
