In the flower plant named Four o’clock, R is the allele for red color and W is allele for white color. Two pink flowered Four o’clock plants were crossed.
Show the possible outcome of the cross between two pink flowered Four o’clock plants by using the Punnett square.
Now, another cross was made involving a redflowered Four o’clock plant and a pink flowered Four o’clock plant.
Using the Punnett square again, show the possible outcome.

In guinea pigs, black fur is dominant over brown fur, and short hair is dominant over long hair. These traits follow Mendelian inheritance. Suppose a homozygous short black hair is mated with a homozygous long brown haired rabbit, determine the phenotypic ratio of the following: F1 generation; F2 generation; F1 mated with a short brown haired rabbit.
Gene Notation: B - hair color , S - hair length
