Jade creates a Punnett square to show the cross
between a parent with freckles and a parent without
freckles. The completed Punnett square shows the
possible genotypes and phenotypes of the offspring.
Jade, however, made a mistake as she was making the
Punnett square. In which part of the Punnett square did
Jade make her error? Be sure to explain your answer.
FrecklesFreckles
Ff
Freckles
No freckles

sample response: Jade's error occurs in the top-right square of the Punnett square. In this square, she identifies the phenotype as freckles, but to have freckles, the offspring must have at least one dominant allele. The offspring in this box are ff. Because there is no dominant allele present, the offspring will not have freckles.

Explanation:

the atomic mass is the bottom number on the element.
