BIOLOGY
CHALLENGE 5 QUIZZ
2
GENETICS
Branch of biology that studies genes, genetic variation and heredity in organisms.
3
Multiple Choice
Who's considered the Father of Genetics due to his experiments with pea plants performed in a monastery?
4
Due to the numerous crosses between the pea plants, he established three laws to describe the mechanisms of inheritance
Law of Dominance
Law of Segregation
Law of Independent Assortment
5
Law of Dominance
States that one allele of the pair will be dominant, thus it will be expressed, while the recessive trait will always be concealed in the presence of this dominant trait.
6
Multiple Select
Mark the genotypes that will express the dominant trait
7
Law of Segregation
States that alleles are "passed" randomly into gametes from the parents, such that half of the parent's gametes carry each allele.
8
Open Ended
Write the genotype that we would get from a cross between a Homozygous Dominant (AA) genotype and a Homozygous Recessive (aa) genotype:
9
Law of Independent Assortment
States that the allele a gamete receives for one gene does not influence the allele received for another gene.
10
Read carefully...
In dogs, the allele for black fur (B) is dominant to the allele for yellow fur (b).
A homozygous black fur dog is crossed with a yellow fur dog.
Read the previous statement a couple of times more before continuing with the following questions.
11
Multiple Choice
After doing the cross between the two dogs we obtained the following results in a Punnet Square, what is the probability of having a yellow fur dog?
12
Open Ended
What is the genotype of the black fur dog?
13
Open Ended
What is the genotype of the yellow fur dog?
14
Reproduction in Living Organisms
15
Multiple Choice
Type of reproduction that requires only one progenitor, and the progeny are genetically alike. Bacteria and many invertebrates reproduce through this method:
16
Multiple Select
Select the conditions that take place in Sexual Reproduction (Multiple Answers)
17
Multiple Choice
If we cut a viable branch of a plant and put it under the right conditions, another entire plant will grow out of it, what Type of Reproduction corresponds to this example?
18
Gamete Exchange
During this process, both progenitors exchange their genetic material through their sex cells (gametes). This only happens during one type of reproduction.
19
Open Ended
What is the name of the male gametes (sex cells)?
20
Multiple Select
What is the name of the female gametes (sex cells)? More than one may apply:
21
Multiple Choice
What is the name of the event where both gametes get in contact with each other, fusing into one single zygote?
22
You can get it too.
Whatever your "it" is.
You're capable.
You've got the power within you.
You have the potential within you
to achieve anything you can
possibly imagine.
All you gotta do is give yourself
the permission to do it, and then
do it.
Be ferocious.
Never lose your North Star.
Stay focused.
I wish you the best, clan.
