Genetics and DNA
This structure contains tightly coiled DNA and is found in the nucleus.
What is a chromosome?
In a heterozygous cross (Aa × Aa), this is the probability of a recessive trait presenting.
What is 25%?
This process produces four genetically different cells.
What is meiosis?
This relationship benefits both organisms.
What is mutualism?
These are environmental conditions that restrict population growth.
What are the limiting factors?
A segment of DNA that codes for a specific trait is called this.
What is a gene?
This term describes an organism with two different alleles.
What is heterozygous?
This type of reproduction results in identical offspring.
What is asexual reproduction?
This relationship benefits one organism while the other is unaffected.
What is commensalism?
This is the ultimate source of energy in most ecosystems.
What is the Sun?
This term describes two identical alleles for a trait.
What is homozygous?
The name of the chart that tracks inheritance of traits across generations.
What is a pedigree?
This process increases genetic variation in a population.
What is sexual reproduction?
This relationship harms one organism while benefiting another.
What is parasitism?
These organisms break down dead material and recycle nutrients.
What are decomposers?
This molecule carries genetic instructions for traits.
What is DNA?
This tool is used to predict the probability of offspring traits.
What is a Punnett square?
This process produces two identical daughter cells.
What is mitosis?
This interaction occurs when one organism hunts and eats another.
What is predation?
This happens to a population when a limiting resource becomes scarce.

Clue: This type of cell division produces gametes.
What is meiosis?
This interaction occurs when organisms compete for limited resources.
What is competition?
This describes how energy moves through trophic levels in an ecosystem.
