Punnett Square Practice
A rabbit with black fur
Bb
Genotypes are the genetic makeup of an individual that is represented by 2 letters. Phenotypes are the physical characteristics of the trait, or what it looks like. Click on the example of a GENOTYPE
Nope! Black fur is the phenotype, or the physical characteristic of the bunny.
Correct!Answer the next question below to continue.
In these flowers, having white flowers is dominant (W) to having pink flowers recessive (w). Using the blank Punnett square below, diagram the genotypes that can result from a cross between a parent flower with white flowers (WW) and another parent flower with pink flowers (ww)

In humans, curly hair (H) is dominant over straight hair (h). Based on the Punnett square below, what is the probability that a child of these parents will have the phenotype of straight hair?
Based on the Punnett square below, what is the probability that a child of these parents will have the phenotype of straight hair? Yes! In order to have STRAIGHT hair, their child must have both recessive genes.

In humans, dimples (D) in the cheeks are considered a dominant trait. The absence of dimples (d) in the cheeks is recessive. Complete the following Punnett square where both parents have genotype Dd. What percentage of their offspring will have Dimples?
