Two ways:
1. In prophase I of meiosis the homologous chromosomes synapse and crossing over occurs. This switches sections of two of the sister chromatids so the outer two chromatids have the same mix of alleles as the parents and the inner two chromatids have new combinations of alleles.
2. Meiosis puts only one of each kind of chromosome in the gametes, selecting one of each homologous pair at random. Then when each gamete joins with the gamete from the other parent, there are practically infinite combinations of the alleles possible.
A long-lasting influence of historical processes on the current ecology of an area is called a legacy effect.
<h3>What is the legacy effect caused by?</h3>
- Legacy effects are alterations to the environment brought on by earlier human disturbances.
- Changes in land use and land cover, fire regime, water diversion, the introduction of chemicals or isotopes, other disruptions of natural processes,
- Or combinations of these changes may all contribute to the disturbance.
<h3>What is an Ecology?</h3>
- Ecology is the study of interactions between living things, such as humans, and their natural surroundings.
- The levels of individuals, populations, communities, ecosystems, and biospheres are all taken into account in ecology.
