Question 11 pts
From Genetics Lecture 2.1, question 1:
If the twins, Thomas and Vincent Seris, (featured in the short documentary

pigmentosum)?
Group of answer choices

c. 25%
d. 0 %
Question 21 pts
From Genetics Lecture 2.1, question 2:
If you were to cross a black and a white guinea pig, what would you expect
in the F1 generation? (keeping in mind that black is the dominant trait)
1. All black offspring
2. All white offspring
3. 3:1 black to white offspring
4. 3:1 white to black offspring
Group of answer choices
A. All black offspring
B. All white offspring
C. 3:1 black to white offspring
D. 3:1 white to black offspring
Question 31 pts
From lecture 2.1, question 3:

the F2 generation?
Parental generation: White x black
F1 generation: ??
F2 generation: ??
Group of answer choices
A. All black offspring
B. All white offspring
C. 3:1 black to white offspring

Question 42 pts
From Lecture 2.1:
Match the following terms to the correct definition.
1. Dihybrid cross – involves breeding organisms heterozygous for two traits, resulting in a
9:3:3:1 phenotypic ratio in the offspring, demonstrating the principle of independent
assortment.
2. Phenotype – the set of observable characteristics of an individual resulting from the
interaction of its genotype with the environment.
3. Genotype – the genetic makeup of an organism, or the combination of genes it inherits.
It's coded in the DNA of an organism's cells.
4. Mendel's Law of Independent Assortment – the alleles of two (or more) different genes
get sorted into gametes independently of one another.
5. Monohybrid cross – a breeding experiment where parents differ in only one trait,
focusing on the inheritance of a single gene, and can be visualized using a Punnett
square.
6. Prophase I – a crucial stage of meiosis where homologous chromosomes pair up,
undergo crossing over (recombination), and condense, ultimately preparing for the
segregation of chromosomes in the subsequent stages.
7. Meiosis – a type of cell division that results in four daughter cells each with half the
number of chromosomes of the parent cell, as in the production of gametes and plant
spores.
