Exploring Punnett Squares in Among Us

The video tutorial explains how to use Punnett squares to predict the offspring of two crewmates, one red and one pink. It covers the concepts of homozygous dominant and recessive traits, setting up a Punnett square, and determining the phenotypes of the offspring. The tutorial emphasizes the difference between genotype and phenotype, illustrating that all offspring will be red due to the dominant trait.

What is the purpose of using a Punnett square in genetics?

• To identify the species of an organism

• To predict the probability of offspring traits

• To determine the age of an organism

• To measure the size of DNA

In the given scenario, what are the colors of the two crewmates?

• Orange and Black

• Yellow and Purple

• Red and Pink

• Blue and Green

What does 'homozygous' mean in genetics?

• Recessive alleles

• Same alleles

• Dominant alleles

• Different alleles

How are dominant traits represented in a Punnett square?

• With lowercase letters

• With numbers

• With capital letters

• With symbols

What is the genotype of the red crewmate?

• Two lowercase r's

• One capital R and one lowercase r

• Two capital R's

• One capital R and one lowercase p

Where do you place the alleles of the first parent in a Punnett square?

• On the left side

• On the right side

• At the top

• At the bottom

What is the probability of the offspring being red if one parent is homozygous dominant and the other is homozygous recessive?

• 100%

• 50%

• 25%

• 0%

What does a phenotype represent?

• The genetic makeup

• The number of chromosomes

• The observable traits

• The DNA sequence

What is the difference between genotype and phenotype?

• Genotype is the observable trait, phenotype is the genetic makeup

• Genotype is the genetic makeup, phenotype is the observable trait

• Genotype and phenotype are the same

• Genotype is the number of chromosomes, phenotype is the DNA sequence
