Last week you were wondering what Jessica and Tom's babies might look like with respect to their eyebrows and earlobes (both Tom
mash [69]

Answer:

25%

Explanation:

The possible genotypes and phenotypes are:

  • EE or Ee: thick eyebrows
  • ee: thin eyebrows
  • FF or Ff: free earlobes
  • ff: attached earlobes

Tom and Jessica have thick eyebrows and free earlobes. Tom's mother has attached earlobes, so Tom must have inherited an <em>f</em> allele from her, and because he has free earlobes he must be heterozygous<em> Ff. </em>We assume Jessica is homozygous for free earlobes <em>FF</em>.

Tom's mother and Jessica's father have thin eyebrows, so they are both <em>ee</em> and therefore both Tom and Jessica must be heterozygous <em>Ee</em>.

From the above information, Tom has the genotype EeFf and Jessica is EeFF. If you do a Punnett Square of this cross, you'll get that the probability of having a child with free earlobes and thin eyebrows (eeF_) is 25%.
