In a strain of tomato plants, short plant height and small fruit size are traits that display autosomal recessive patterns of inheritance.  To investigate whether the traits segregate independently, researchers cross a pure-breeding line of tall tomato plants that have large fruits with a pure-breeding line of short tomato plants that have small fruits.  The researchers observe that all the plants in the F1 generation are tall and have large fruits.  The researchers cross the F1 plants with one another to generate an F2 generation.  The researchers record observations for the F2 generation.  The researchers choose a significance level of p = 0.05.  Which of the following best completes the chi-square goodness-of-fit test? A. Restate the question and record the right answer. B. Why is this the correct answer?

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.
