Photosynthesis takes place
Answer:
Pea plant flowers of two colors were used i.e., Purple and White. He observed the same ratio in both cases (3:1), in the self and cross pollination. This happens because of the assumptions in Law of Segregation and Law of Independent assortment. He concluded that the purple color is the Dominant and white in recessive as in both self and cross pollination procedures.
Potable water is water that is safe to drink
Answer:
It is possible to compare the expression of homologous genes in the brain of <em>D. melanoganster</em> and humans, because the expression levels of conserved genes may be associated with the evolution of cognitive features such as complex learning and memory.
Explanation:
Model organisms can be used to understand the patterns and processes that affect human evolution. <em>Drosophila melanogaster </em>is a model organism that has been used to study expression patterns of conserved genes in the course of evolution. This model organism has also been used to develop genetic mutant lines in order to examine the role of genes evolutionarily conserved in animals, including those involved in neurocognitive development.
In genetic research, an experiment as the above described is framed in a research field named 'Behavioral Genetics', which is a discipline that studies how evolutionarily conserved gene networks may be associated with neurocognitive tasks during brain evolution.
