A Hands-On Exercise To Demonstrate Evolution
... Evolution can occur through processes other than natural selection. The second exercise demonstrates how genetic drift can lead to changes in phenotype through a random association between phenotype and fitness. Such changes are not usually adaptive (by definition) and generally do not contribute to ...

Selection against Accumulating Mutations in Niche

Our current understanding of sympatric speciation is that it occurs primarily through disruptive selection on ecological genes driven by competition, followed by reproductive isolation through reinforcement-like selection against inferior intermediates/heterozygotes. Our evolutionary model of select ...

Section 9.1 – Sensory Reception
... Rod cells breakdown the pigment rhodopsin to generate an action potential. Rhodopsin is easily broken down in low light intensity Since more that one rod cell is connected to the same neuron, only one impulse will be generated. It is impossible for the brain to determine which rod cells were stimula ...

Dosage compensation: do birds do it as well?

For one of the nine genes analysed by quantitative RT–PCR, ScII, expression levels were consistently twice as high in males as in females [4]. This might suggest that some avian ...
