Question
Karen is right handed (Hh) and married Clint, who is left handed (hh). What are the chances their child will be left handed?
Answers

To determine the chances of their child being left-handed, we need to consider the genetic inheritance of hand dominance.
Since Karen is right-handed (Hh), she carries both the dominant allele (H) for right-handedness and the recessive allele (h) for left-handedness. On the other hand, Clint is left-handed (hh), carrying two copies of the recessive allele (h) for left-handedness.
To calculate the probability, we need to use a Punnett square. Cross Karen's alleles (Hh) with Clint's alleles (hh):
h h
H | Hh Hh
h | Hh Hh
From the Punnett square, we can see the following:
- There is a 50% chance that the child will inherit the allele for left-handedness (h) from Karen.
- There is a 100% chance that the child will inherit the allele for left-handedness (h) from Clint.
Therefore, the chances of their child being left-handed is 50% (from Karen) multiplied by 100% (from Clint), which equals a 50% chance.
