Select all of the example that represent biological evolution horses that get more exercise become stronger and will have foals that are stronger the number of individuals witht eh type o blood genotypes increases in a small human population size due to a reduction in population size one species from the mianland diverges into two distinct species on a group of islands indivduals in a population exposed to high levels of ultraviolet light become blind as adults and will have offspring that re also blind the frequency of the gene for sickle-cell anemia in a human populationd decreases from 0.002% to 0.001%

Reproductive isolation leads to induced mutations emergence of separate species immunity to genetic drift high rates of gene flow

I need help with a biology question: Sometimes a restriction in genetic variability is imposed on populations by natural catastrophes such as flooding, earthquake, etc. The surviving individuals reflect only a small, random genetic sample of the population affected. This process is termed    sudden mutation the founder effect non random mating gene flow

A farmer wants to make a better corn plant that produces more and bigger kernels. In the chart, information is provided on two ways organisms can change over time. Natural Selection Selective Breeding Humans are not involved in the evolution process Human intervention is involved More generations are involved in natural selection, so it is a slower process Selective breeding is a faster process Survival of the fittest increases species' chance for survival Adaptations may not necessarily improve survival Mutations that result in natural selection occur randomly The desirable charactenstics are artificially chosen What is the best way for the farmer to improve his crop and why? Use evidence from the table to support your reasoning. Please write in complete sentences.

In which population is evolution by natural selection most clearly demonstrated? Group of answer choices A virus sweeps through a population and makes everyone ill.  A virus sweeps through a population and kills 10% of infants. It is not clear why some die and some don't. A virus sweeps through a population and kills 20% of the population. It is not clear why some die and some don't. A virus sweeps through a population and permanently sterilizes the 10% of the population that has allele hx25c.

Think about the ways we define/identify a species. What would the least precise way to determine a living species (so not extinct)? O groups of organisms that look alike O groups of organisms that are geographically separated for a significant period of time such that they become distinct genetically separate populations with different genetic markers groups of potentially interbreeding populations with are reproductively isolated from others

Imagine a group of adventurous people board a boat and leave for another continent. When they get there, they began to prosper and grow in size. After a few generations, some of the families experience an abnormally high number of birth defects, of the same type. This population is probably experiencing: O Kin Selection Founder Effect O Natural Selection O Post-Zygotic Isolation

What force, which changes gene frequencies, occurs if there is a failure to reproduce or if individuals become isolated from the rest of their population?         mutation         radiation         genetic drift         nonrandom mating

Dog breeders use selective breeding, also called artificial selection, to maintain a closed genetic lineage, and produce offspring with desirable traits. This violates which Hardy-Weinberg condition? a reproduction b no mutation c random mating d no natural selection
