Lamarck's theory of evolution was largely rejected because

In a population of 500 beetles, 320 are green and 180 are brown. If green colour is determined by allele G and brown by allele g, and the population is in Hardy-Weinberg equilibrium, what is the appro…

The peppered moth (Biston betularia) exists in a light-coloured form and a dark-coloured (melanic) form. During the Industrial Revolution in England, the dark form became more common in polluted, soot…

In a population of 500 beetles, 320 are green (dominant) and 180 are brown (recessive). Assuming Hardy-Weinberg equilibrium, what is the approximate frequency of the dominant allele G?

The existence of similar bone arrangements in the forelimbs of humans, bats, whales and horses is used as evidence for evolution. This type of evidence is referred to as
