Cross a heterozygous brown guinea pig with a homozygous white guinea

pig (bb). This is the probability of obtaining white offspring.

Continue

200

If you cross Nn x Nn, this percentage of the offspring will express the

dominant phenotype?

Continue

300

A person with polydactyly (extra digits) is heterozygous and marries and has kids with a homozygous recessive individual.

What is the chance their first child will have polydactyly? (hint: polydactyly is an

autosomal dominant trait)

Continue

400

A trait that is expressed is referred to as __________________

A “bushy eyebrow” father marries a mother that is

homozygous recessive (bb) for “skinny eyebrows”. They

have 4 kids: 1 with bushy eyebrows and 3 with skinny

eyebrows. What is the father’s genotype?

Laura has female pattern baldness (sex-linked, recessive). She marries

Ben who is not bald. What percent of their daughters will have female

pattern baldness. (construct a sex-linked Punnett square to find out!)

Continue

1000

This Punnett square demonstrates a
