1.True or false: If the Hardy-Weinberg equation predicted a homozygous recessive genotype frequency of 0.16, and you found that 16% of the individuals in the next generation had the recessive phenotype for the trait in question, this would mean the trait is evolving. 2.True or false: It is theoretically possible for a population to NOT evolve for some amount of time 3.true of false.In the "energy expansion" hypothesis that explains the sequence of major events in the history of life, different forms of energy, each containing more available energy then the previous, become available to life over time. 4.True or false: A mutation that effects the phenotype of an organism can be either adaptive or harmful depending on the selective environment 5.True or false: In sexually reproducing organisms theory predicts that speciation will occur when reproductive isolation is achieved. For this to occur, a population must be physically separated into two or more isolated locations. 6.True or false: When Peter and Rosemary Grant observed droughts in their long term data set about finch beak size, the droughts always cause the average size of finch beaks to increase. 7.True or false: Because species evolve through natural selection, where more "fit" individuals are more likely to survive, overtime evolution results in species becoming better and better, making "progress" towards a more perfect form that is better at everything.
Gene Flow
Gene flow, also known as gene migration, is the introduction of genetic material from a particular population to another population of the same species through interbreeding. For example, a bee facilitates its reproductive process by carrying pollen from one flower to another. The flow alters the composition of the gene pool of the receiving population. It introduces new alleles within the population and helps increase variability. This exchange of genetic material occurs through reproduction and brings about new combinations of traits into the population. Where human beings are concerned, actual migration of populations, whether voluntary or forced, brings about gene flow.
Population Biology
Population biology is the study of patterns in organism populations, specifically the growth and management of population size, population genetics, the evolution of life history, species interactions, and demography.
Speciation
The process of speciation involves the formation of new species during evolution. The new species evolve in such a way that both new and old species are not able to interbreed. Thus, speciation occurs when few members of one species get separated from the main species due to geographical, mechanical, or reproductive isolation. These separated members develop new traits that make them different from the main species. In other words, speciation could be defined as the absence of gene flow between two populations that become new species.
Allele Fixation
A gene is a unit of heredity and contains both physical and functional information that shapes an individual. Genes are made up of DNA (deoxyribonucleic acid), which carry genetic information from one generation to another, from one set of parents to their offspring, and so on. Every cell in a human body, or any living organism, has the same DNA, which implies that every cell in an individual’s body has all the information it needs to build and sustain the body!
