In natural selection, the product of variations is because of ________

Theory of natural selection of organisms states that organisms that are best adapted to the environment _______

Which statement is correct with respect to the food chain?

An orchid living on a tree exhibit____________.

Shelford’s law of tolerance suggests that organisms with a wide tolerance limit for environmental factors show:

What is the name of the trait that helps creatures to live in their environment?

Which of the following is NOT a condition for Hardy-Weinberg Equilibrium?

According to the Hardy-Weinberg equilibrium, if no unfavorable influences exist, genetic variation in a population will remain stable from one generation to the next. Furthermore, because genotype and allele frequencies are in equilibrium when mating is random in a large population with no disruptive influences, the rule predicts that they will remain constant.
• When a population reaches Hardy-Weinberg equilibrium for a gene, it is not evolving, and allele frequencies do not alter over time.
• The five fundamental Hardy-Weinberg assumptions are that there is no mutation, random mating, no gene flow, an infinite population size, and no selection.
• A gene's population may evolve (the allele frequencies of the gene may change) if the presumptions are not true for that gene.

What does the Hardy-Weinberg equilibrium measure?

What is the name of the process in which the most favourable traits are passed onto the next generation?

Which of the following cannot introduce new alleles into a population's gene pool?

All of the alleles found in a population.

The type of genetic drift that follows the colonization of a new habitat by a small group of individuals is called __________.
