- genes are carried on
- continuous variation
- a a diploid organism whose chromosomes have two copies of the SAME allele. Opposite of heterozygous
- b chromosomes
- c ex: height in humans, birthweight
- d a FEATURE of an organism CREATED by the process of natural selection.
- e the form and structure of an organism
5 Multiple choice questions
- a hypothesis that speciation can result from selective pressures favoring different phenotypes within a population without geographic isolation as a factor
- the genetic makeup of a trait
- a steady state in which two or more alleles coexist in a population.
- the transfer of alleles of genes from one population to another
- selection pressuresd that favor average phenotypes. Stabilizing sleection reduces the amount of variation in the population but doesn't alter the mean value of the trait.
5 True/False questions
allopatric speciation → a hypothesis that speciation can result from selective pressures favoring different phenotypes within a population without geographic isolation as a factor
polygenic → many genes?
discontinuous variation → phenotypic variation in which there are a discrete number of phenotypes with no intermediate types. Ex: pea color in Mendel's experiment
chromosomes → carries genes and appears during cell division
natural selection → where a single phenotype is favored, causing the allele frequency to continuously shift in one direction
