Potpourri
A group of individuals that belong to the same species and live near each other
What is a population?
The instructions for proteins.
What is DNA?
Fruit flies are an example of a species that uses this type of reproduction.
What is sexual reproduction?
This type of mutation improves an organism's chance of survival by providing it with a new trait.
What is a beneficial mutation?
The father of genetics
Who is Gregor Mendel?
The study of how genes are passed on from one generation to the next.
These are located on chromosomes and control specific traits.
What are genes?
This type of reproduction results in the offspring having the same exact genes as the parent.
What is asexual reproduction?
Albinism is this type of mutation.
What is a harmful mutation?
Humans can increase the number of albino squirrels in a population by doing one of these things.
Selective breeding
Removing grey squirrels
Creating laws to protect albino squirrels
Feeding/housing albino squirrels
Having two of the same alleles.
What is homozygous?
Melanin is both a ________ and a __________.
What is pigment and protein?
The percent chance of offspring being heterozygous when each parent is homozygous for a different trait.
What is 100%
A mutation that does not affect the structure or function of the protein that it creates would be called this type of mutation.
What is a neutral mutation?
The breeding of two organisms that are closely related and have similar traits and genes.
This type of chart/image shows all the chromosomes of a certain organisms. The chromosomes are organized into pairs.
What is a karyotype?
A change in DNA that may or may not result in a change to a protein.
What is a mutation?
This chart shows the inheritance of a certain trait over multiple generations of a family of organisms.
What is a pedigree?
Sickle Cell anemia in humans is this type of mutation.
What is a harmful mutation?
This practice has both positive and negative effects on certain species. The positive effects are that organisms develop traits that humans find useful. The negative effects are usually that the organisms have a higher likelihood of inheriting genetic diseases.
What is selective breeding?
The stripes that are visible on a chromosome are referred to as its ____________.
What is banding pattern?
A specific form of a gene that is the instructions for a certain variation of a trait.
What is an allele?
In species that produce asexually, there is less ____________________ because the parents and offspring share the exact same DNA. This can increase the prevalence of genetic diseases in a population.
What is genetic variation?
Albinism results from a mutation that causes the ___________ of melanin to change so that it no longer __________.
What is: structure, functions?
Give an example of a human action that negatively affects the survival of a specific species.
Answers will vary.
