Mendelian Genetics with Marvel Superheroes

Front

What are alleles?

Back

Alleles are alternate versions of the same gene that determine specific traits.

Front

What does homozygous dominant mean?

Back

Homozygous dominant refers to having two identical dominant alleles for a trait, such as WW.

Front

What is the expected phenotypic ratio of offspring from two heterozygous parents (NnFf)?

Back

The expected phenotypic ratio is 9:3:3:1.

Front

What is the genotypic ratio of offspring from a Ww (Spider-Man) and ww (Mary Jane Watson) cross?

Back

The genotypic ratio is 1:1.

Front

What is Mendel's Law of Dominance?

Back

Mendel's Law of Dominance states that in a heterozygote, one allele may conceal the presence of another.

Front

What is a phenotype?

Back

A phenotype is the observable physical or biochemical characteristics of an organism, determined by its genotype.

Front

What is a genotype?

Back

A genotype is the genetic constitution of an individual, represented by the alleles it possesses.

Front

What does heterozygous mean?

Back

Heterozygous refers to having two different alleles for a particular gene, such as Ww.

Front

What is Mendel's Law of Segregation?

Back

Mendel's Law of Segregation states that during the formation of gametes, the two alleles for a trait separate from each other.

Front

What is Mendel's Law of Independent Assortment?

Back

Mendel's Law of Independent Assortment states that alleles for different traits are distributed to gametes independently of one another.
