40 Questions
Nicolaus Steno was the father of modern taxonomy.
False
The theory of evolution by natural selection was first conceived by Charles Darwin and Thomas Malthus.
False
The idea of homology is most closely associated with the theory of gradualism.
False
Evolution can happen without any variation in the population.
False
Mutation by itself is not an important factor in evolution.
False
Inbreeding has a positive impact on the genetic structure of a population.
False
Thomas Malthus is best known for his idea that evolution occurs through natural selection.
False
The person who first accurately described fossils as remnants of things that lived in the past was Charles Darwin.
False
Darwin's idea of natural selection was influenced by the concept of uniformitarianism put forward by Charles Lyell and James Hutton.
True
Evolution can be considered a fact because it is a proven and unchanging scientific theory.
False
What are the assumptions for a population to be in Hardy-Weinberg equilibrium?
Random mating, no natural selection, large population, no mutation, and no migration
If a population in Hardy-Weinberg equilibrium undergoes a round of random mating, what happens to the allele and genotype frequencies?
They remain unchanged
What is microevolution?
Evolution occurring on a small scale within a single population
Can evolution happen without variation in the population? Why or why not?
No, because genetic variation is necessary for natural selection and adaptation to occur
What is an allele?
A specific form of a gene that codes for a particular trait
Is mutation by itself an important factor in evolution?
Yes, because mutations are the primary source of genetic variation
What is natural selection? Is it random? What is the outcome of natural selection?
The process by which organisms better adapted to their environment survive and reproduce, leading to evolutionary changes; It is non-random; The outcome is adaptation of the population to its environment
What is an adaptation?
A characteristic that enhances an organism's survival and reproduction in its environment due to its genetic composition
The phrase “modern synthesis” refers to:
The integration of genetics with Darwin's theory of evolution by natural selection
How is mutation a force of evolution? Is it weak or strong? Why?
Mutation introduces genetic variation which can be acted upon by natural selection; It is weak because most mutations are harmful or neutral
What is inbreeding?
A type of non-random mating that increases homozygosity
What is the consequence of inbreeding on the genetic structure of a population?
Increases the frequency of homozygous individuals
What are two kinds of non-random mating?
Assortative mating and inbreeding
What is evolutionary fitness?
The ability of an organism to survive and reproduce in its environment
Is mutation by itself an important factor in evolution?
Yes, mutation alone drives most evolutionary changes
What is inbreeding?
The process of mating closely related individuals within a population.
How does inbreeding impact the genetic structure of a population?
It decreases genetic diversity and increases the risk of inherited genetic disorders.
What is a potential consequence of extensive inbreeding within a population?
Decreased fitness and survival rates.
In the context of evolution, how does inbreeding affect the probability of expressing harmful recessive traits?
It increases the probability due to the presence of identical genetic material.
What is the impact of inbreeding on the overall health and viability of a population?
It leads to reduced overall health and viability due to genetic homogeneity and increased disease susceptibility.
What is inbreeding?
The mating of individuals that are closely related
What is a common misconception about inbreeding?
It always leads to increased genetic diversity
How does inbreeding affect the genetic makeup of a population?
It increases the frequency of rare alleles
What is a potential consequence of inbreeding in a population?
Increased expression of deleterious traits
Why is inbreeding a challenge to the biological species concept (BSC)?
It weakens the reproductive isolation between species
What is inbreeding?
The mating of closely related individuals within a population
What impact does inbreeding have on the genetic structure of a population?
It promotes heterozygosity in the population
How does inbreeding differ from intersexual selection?
Inbreeding involves mating between closely related individuals, while intersexual selection involves differential mating based on certain traits
Why is inbreeding generally considered detrimental to populations?
It can result in the expression of harmful recessive traits and reduce genetic diversity
What is the primary concern when it comes to inbreeding depression?
The decreased genetic diversity within the population
