4. Two genes control color in lentils. A- B- lentils are black, A- bb are cream, aa B- are brown, and aa bb are white. A black lentil plant was crossed to a white lentil and all F1 progeny were black. F1 lentils were crossed to each other and you observe 105 black, 27 cream, 24 brown, and 14 white. 4A. What are the genotypes of the F1 lentils? A. A mix of A-B- genotypes. B. AaBb C. Can't say Answer: 4B. Rounding down any expected progeny to the nearest whole number, what is the Chi squared statistic (rounded to tenths place) for whether your observed progeny fit your expectation for unlinked genes? Answer: 4C. What is the statistical significance of this value? (use the contingency table in the book). 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.
