Which of Mendel's laws is shown here?
Law of Genetics
Law of Gamete Formation
Law of Independent Assortment
Law of Segregation
With mono and di hybrid crosses, why do we have to use some many allele combinations?
Alleles randomly distribute during gamete formation.
Alleles have a set formation.
We have to calculate Mom alleles first then Dad
Alleles are dominate and recessive

0%
25%
50%
100%

Identify if there is or isn't something wrong in the picture.
Nothing is wrong
Chromosomes didn't separate correctly
There are not enough gametes formed.
Too many starting chromosomes
In a sex linked question, can a female offspring ever inherit the father's Y chromosome?
Yes
No
In a sex linked question, can a male offspring ever inherit the father's X chromosome?
Yes
No
I need the genotype of the second generation child 3, if Mom is autozomal recessive blonde hair and dad is autozomal dominate brown hair

What is the genotype for generation 2 child 5? If we are tracking baldness (recessive) on the x-chromosome.
xB xb
xB yb
xB xB
xb xb
In order for a female to be affected with a recessive trait, such as baldness.
Her Y chromosome must have the recessive allele.
Both her X and Y chromosome must have the recessive allele.
Her one X chromosome must have the recessive allele.
Both her X chromosomes must have the recessive allele.
In codominance, which statement is true?
Both alleles are expressed in a heterogeneous situation.
Nothing is expressed
Only one allele is expressed

Genetic drift is what?
When we see a slow changed in the allele frequency in a population.
When we see organisms start to mutate.
When organisms eat and prey upon another
When you drift asleep in class.
These poor beetles are experiencing what type of genetic drift?
Bottle Neck Effect
Founder Effect
Sexual Selection
Natural Selection
Example are two moths in nature, one is going to be preyed upon easier because he isn't adapted to their environment.
Natural Selection
Sexual Selection
Bottleneck Effect
Founder Effect
Select all the biotic factors
Cat
Plant
Bacteria
Water
Soil
Select all the abiotic factors
Lighting
Wind
Cat
Plant
Bird
This type of genetic drift involves the initial population not dying, but a random group leaving and starting a new colony somewhere else.
Founder Effect
Natural Selection
Sexual Selection
Bottleneck Effects
Female cardinals only select the red-est males to mate with, this is sexual selection. What happens to the gene pool of males with not as red color?
No change in the cardinal population color.
Lighter red color cardinals will not be able to mate
The females will kill the lighter red males.
The brighter red males will kill the lighter red males.
This type of natural selection favors one of the extremes.
Directional
Stabilizing
Disruptive
Natural
