- what's a nucleotide composed of?
- allopatric speciation
- continuous variation
- a ex: height in humans, birthweight
- b a phosphate-sugar base
- c opposite of punctuated equilibrium
- d a diploid organism whose chromosomes have two copies of the SAME allele. Opposite of heterozygous
- e speciation that occurs when two or more populations of a single species are geographically isolated from each other and then diverge to form two or more new species
5 Multiple choice questions
- carries genes and appears during cell division
- DNA is double stranded while RNA is single stranded, DNA has only a nucleus but RNA can have a nucleus or a cytoplasm, the main ingredient in DNA is Thymine while in RNA it's Uracil.
- the genetic makeup of a trait
- the shown trait
- a steady state in which two or more alleles coexist in a population.
5 True/False questions
adaptive radiation → the process in which a single lineage diversifies into a number of species
discontinuous variation → ex: height in humans, birthweight
genes are carried on → chromosomes
reproductive isolation → driving force behind sympatric speciation extreme values for a trait are favored over intermediate values. E.g.: large nose rather than medium sized nose
stabilizing selection → 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.
