Make a Baby Lab Section 2: Predictions

Considering the genotypes of you and your partner, predict which phenotype you would most likely see passed on to your offspring for at least 5 traits. Base your predictions

To accomplish this, on your traits inventory sheet, there are a five traits that have simple inheritance patterns (not incompletely dominant or polygenic):

Face shape Possible phenotypes: round (dominant) or square (recessive) Possible genotypes RR, Rr, rr

Eyebrows Possible phenotypes: not connected (dominant) or unibrow (recessive) Possible genotypes NN, Nn,nn

Earlobes Possible phenotypes: free (dominant) or attached (dominant) Possible genotypes FF, Ff, ff

Freckles Possible phenotypes: present (dominant) or absent (recessive) Possible genotypes PP, Pp, pp

Dimples Possible phenotypes: present (dominant) or absent (recessive) Possible genotypes KK, Kk, kk

Using the two genotypes of you and your partner from your Traits Inventory sheet, you are to create a Punnett square to predict the likelihood of your children having the dominant and recessive phenotype for each of those traits.

For this submission you will have a page showing FIVE Punnett squares, and the odds of your child having the dominant or recessive phenotype for each trait.

As a challenge — choose an incompletely dominant trait and do a Punnett square for the trait, determining the likelihood of your children having the each of the three possible phenotypes.
