4. Barb Wyre, a plant geneticist at the UK Ag Experiment Station, has set up a cross between two tobacco plants - one is heterozygous for three genes, and the other is homozygous recessive for the same three genes. She sows the F1 progeny seeds in the field; unfortunately, a hailstorm destroys some of her plants. Fortunately, she has enough survivors to permit an accurate statistical analysis of the cross, and she proceeds. The adult F1 plants exhibit the following phenotypes: OPS- OPS Op S OPS Ops 96 OPS - 110 op S - 306 ops 63 111 ||||I 73 348 - 2 16 Construct a map of the three genes.

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.
