Evolution

QuestionAnswer
What type of reproduction that creates identical offspring? asexual
What process produces non-identical gametes? meiosis
Genetic variability is created by sexual reproduction, different alleles for a gene and what? mutations
What are alternate forms of a gene called? alleles
What type of reproduction leads to genetic variability? sexual reproduction
Gametes produced through meiosis are not identical because of independent assortment AND what process? crossing over
A beneficial one of these can lead to a new allele for a gene. A harmful one of these often leads to genetic defects and death mutations
The gene for eye color might have a blue and brown one of these? alleles
If an organism has two different alleles for a trait they are said to be what? heterozygous
If a population is at a genetic equilibrium (gene frequencies remain the same) then evolution is or is not occurring? is NOT.
If natural selection is favoring a particular form of a trait and non of the other forms (black color only) then what type of selection is most likely occurring? directional
If a population is undergoing evolution then the frequency of genes is changing or not changing? changing
An individual who is Bb is a carrier of a recessive allele which promotes genetic variability. A Bb individual for a trait is said to be what? heterozygous
If a population is stable with 30% black and 70% brown, the population is in what? genetic equilibrium.
If natural selection is favoring two extreme forms of a trait (black and white but not brown), what type of selection is most likely occurring? disruptive
If natural selection is favoring the most common form of a trait then what type of selection is most likely occurring? stabilizing
