Woody Guthrie, who wrote This Land is Your Land, was heterozygous for Huntington’s disease (Hh). His wife was homozygous recessive and perfectly normal (hh). Huntington’s disease is caused by a latent dominant gene, meaning that it is not phenotypically (physically) expressed until later in life. Dominant disease genes are expressed in homozygous dominant and heterozygous people (HH or Hh). Draw a Punnett square for Woody ad his wife.

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
