Question

dividuals in a population vary, and more offspring are produced than can be supported by current resources. Some offspring die and those with greater ability to survive and reproduce are selected for. 3. An organism's capability to survive and reproduce is called its C 4. When species evolve better fitness it is called 5. When species evolve to accomodate changes in their natural environment it is called selection, whereas humans can selectively breed animals to promote selection. 6. Most evolution involves species becoming progressively more different, termed evolution. But, in some cases, bird and bat wings develop in unrelated species. This latter case is calledevolution. Population Genetics 1. Match the following terms with the best description: a. Gene pool l of the genetic Inlormation in a population b. Fixed Allele Acrumstance when there is only a single variant of a gene c. Microevolution Changes in d. Macroevolution The emergence of new species e. Average Heterozygosity Ameasure of genetic variabity in a population f Cline Agradient of genetic changes across a geographical space aliele fr y in a population 2. Hardy-Weinberg Equilibrium- Developed a model of populations that are not evolving. This model makes a series of assumptions that make it impossible but the model represents an estimation about real populations. a. Which of the following is not an assumption of Hardy-Weinberg equilibrium? v Each b. Dwarfism is a dominant Mendelian trait. If a population of 500 individuals is at equilibrium and there are 375 dwarfs how many of those are carriers? How many people in the population are not dwarf? ( What proportion of people in the population are not dwarf? ( What proportion of the population are heterozygous? O How many people in the population are heterozygous? (bound up) ( 3. Real populations change in ways that cannot be predicted by Hardy-Weinberg equilibrium: a. They under go non-random mating, called ( b. Sometimes natural disasters can eliminate a large segement of the population to create an evolutionary ( c. Gametes may cross from one population to another, called ( (two words). effect (nwo words).
