Free earlobes are dominant over attached earlobes. What is the probability that a woman with attached earlobes (homozygous reces
AVprozaik [17]
<h2>The correct answer is explained below:</h2>

Explanation:

  • According to the question, free ear lobes are dominant over attached ear lobes.
  • Let the allele for free ear lobes be represented by F.
  • Let the allele for attached ear lobes be represented by f.
  • The genotype of the homozygous recessive woman (mother) having attached ear lobes is : ff.
  • The gamete produced by the woman is: f.
  • The genotype of the heterozygous man (father) with free earlobes is: Ff.
  • The gametes produced by the man are: F and f.
  • Mating the man with the woman we get the following offspring,

                                        F                                            f

                           f           Ff                                          ff

          Phenotype      Free ear lobe                   Attached ear lobe

  • The genotype and the phenotype of the probable children obtained is represented in the Punnett square above.
  • The probability that the parents would produce children with attached ear lobes is = \frac{1}{2} .
