genetic drift
Pregunta 15
Pregunta
Immigration is always good.
Respuesta
- True
- False
Pregunta 16
Pregunta
Horizontal gene transfer is when genes from one species are introduced into another organism compared to vertical (parent to offspring) transmission.
Respuesta
- True
- False
Pregunta 17
Pregunta
Horizontal gene transfer....
Respuesta
-
allows for rapid acquisition of traits
-
more common among eukarya
-
more common among bacteria
-
slows down the acquisition of traits
Pregunta 18
Pregunta
Modern [blank_start]Synthesis[blank_end] demonstrated that [blank_start]natural[blank_end] selection operating on Mendelian variation could lead to rates of evolutionary changes that explain historical patterns of evolution.
Respuesta
-
Synthesis
-
natural
Pregunta 19
Pregunta
What equation allows evolution to be documented and qualified? [blank_start]HW[blank_end]
Respuesta
-
HW
Pregunta 20
Pregunta
Hardy-Weinberg Theroem serves as a null hypothesis for whether evolution is occurring in a population. It assumes...
Respuesta
-
small population
-
large population
-
random mating
-
every genotype has the same probability of mating
-
immigration
-
no immigration
-
emigration
-
no emigration
-
equal fitness
-
mutations
Pregunta 21
Pregunta
HW assumptions are important because any [blank_start]violation[blank_end] is a way that [blank_start]evolution[blank_end] can occur.
Respuesta
-
violation
-
evolution
Pregunta 22
Pregunta
If a difference of frequency is found between the actual and expected alleles/genotypes, then evolution has occurred/
Respuesta
- True
- False

Pregunta
You should practice the math questions at the end of this powerpoint.
Respuesta
- True
- False
