Which of the following is incorrect regards genomic imprinting?

#Unit 8. Inheritance Biology
  1. Certain mutations showing lethality if the mutant gene is derived from one parent, but that same mutant gene has no deleterious effects if inherited from the other parent

  2. Genes on autosomal chromosomes that are more readily expressed in one sex

  3. Transgenic male passes an imprinted gene to his offspring, they express the gene; but, when his daughter transmits the same gene to her offspring, they don’t express it

  4. Genes whose expression is affected by the sex of the transmitting parent

The question refers to the following table, which compares the percent sequence homology of four different parts (two introns and two exons) of a gene that is found in five different eukaryotic species. Each part is numbered to indicate its distance from the promoter (for example, Intron I is the one closest to the promoter). The data reported for species A were obtained by comparing DNA from one member of species A to another member of species A.

Regarding these sequence homology data, the principle of maximum parsimony would be applicable in ________.
