Biology Questions

1. Elaborate Mating Displays2 Direct combat3. Sperm competition (during/after copulation)

If slope trendline is closer to 1, then it is heritable. Vice versa yields the opposite result

The similarities in the genome sequence represent the pre-branching genome, and the differences in humans and chimps hints towards speciation

1. 100% of your genetic information is passed on2. Efficient use of eggs

1. 2 groups of similar birds2. Some individuals move between populations through random migration causing gene flow3. Natural disaster occurs, barring migration and gene flow. 4. Natural selection and sexual selection continues in the 2 populations, creating new traits in both populations5. If now reintroduced, females from one group will most likely not reproduce with the other group 6. Genetic drift and mutation continue to accumulate genetic differences between the 2 groups and eventually creates a new species

Males=Sperm's fitness is limited by the ability to attract mates. Maximization of offspring #Females=Egg fitness is limited by an ability to gain the resources required to produce eggs and rear young. Maximization of quality

Branches=represent populations evolving through timeNodes=represent points in time when populations diverge

A collection of branches and nodes that includes an ancestor and all of its descendants

A permanent change to the DNA sequence (produces new alleles)

Descent with modification, but inherited modifications are gained from individual parent's who developed traits within their lifetime. Generation by generation

If mutation acquisition was a random process and present before the presence of any selection pressure, then there would be high variation among survivability of bacterial plates. If not, the variance would be low since acquired mutation hypothesis would state that any organism could mutate to deter a stressor. The variance was extremely high in the experiment

Mendelian describes transmission of alleles from individual parents to individual offspring, while population genetics describes relationship of allele transmission of alleles in populations

A collection of gametes; the set of all alleles that could potentially contribute to the next generation

Descent with modification, in which populations respond to changes in environments and natural selection

1. Happen very slowly2. Alone are not responsible for selection pressure3. Add new alleles every generation 4. Tend to work in opposite direction of selection

1. Descent with modification2. Evolution happens to populations, not individuals3. Natural selection through sorting not transforming

1. Earth developed recently2. Independently (species are unrelated)3. Species were made in their present form (species do not change through time)

1. No mutation 2. Random mating3. No gene flow4. Infinite population size5. No selection

Both species evolved from a common ancestor, but no; it was a branching tree that included an entire phylogeny of branching events

1. Young-Earth Creationism2. Lamarck: Evolution by Inheritance of Acquired Characteristics3. Darwin: Evolution by Natural Selection
