There are 2 wolves per square kilometer in a certain area of northern Michigan. What population characteristic is this?
population density

If you cross an individual that is heterozygous for a trait with an individual that is homozygous recessive for the same trait, what is the probability that an offspring could also be homozygous recessive?
50%

THESE are a pair of chromosomes, each one coming from a different parent
when a population’s growth slows and then stops, following a period of exponential growth
logistic growth
300
Type of inheritance in which expression of both alleles is observed as a distinct phenotype in the heterozygous individual where both the dominant and recessive traits are observed at the same time
codominance
300
Homologous chromosomes pair up to form _________.
tetrads
300
When members of different populations are so different that they can no longer mate successfully - the final step of speciation.
reproductive isolation
400
Similar body structures shared by related species that have been inherited from a common ancestor
Homologous
400
maximum number of individuals of a species that an environment can consistently support.
carrying capcity
400
Type of inheritance in which 1 trait is controlled by two or more genes
Epistasis
400
The failure of chromosomes or chromatids to separate during meiosis
nondisjunction
400
A measurement of how common a certain allele is in the population
allele frequency
500
The process by which organisms with variations most suited to their local environment survive and leave more offspring.
Natural Selection
