Mendelian Genetics with Marvel Superheroes

Spider-Man has two alternate versions of the web gene, W and w. These alternate versions of the same gene are called

• alleles.

• traits.

• characters.

Thor has a widow's peak (V-shaped hairline) because he has the allele combination WW. This makes Thor

• homozygous dominant.

• homozygous recessive.

• heterozygous.

Ironically, Black Widow has no widow's peak because she is homozygous recessive for the gene. In other words, her genotype would be

• straight hairline.

• WW.

• Ww.

• ww.

Black Panther is has the genotype Pp, where P = panther and p = non-panther. However, he shows the panther phenotype. This is an example of Mendel's Law of

• Dominance.

• Segregation.

• Independent Assortment.

Captain Marvel is heterozygous for the flamefist gene (Ff). When she produces gametes, 50% get the F allele, and 50% get the f allele. This is an example of Mendel's Law of

• Dominance.

• Segregation.

• Independent Assortment.

Hulk's father was true-breeding for the green skin and Hulk's mother was true-breeding for non-green skin. This makes Hulk

• true-breeding.

• a hybrid.

If Captain America's genotype is SsRR, what types of gametes will he produce?

• SR, Sr, sR, sr

• SR, SR, sR, sR

• SR, SR, SR, SR

• sr, sr, sr, sr

Nick Fury has the genotype NnFf. If he has children with a woman whose genotype is also NnFf, then the expected phenotypic ratio of the children would be

• 1:3.

• 1:2:1.

• 1:1:1:1.

• 9:3:3:1.
