Graded Assignment

Lab Report: Genetic Crosses 2

The Lab Report contains special characters that may be difficult to enter into the online document. You may complete the Lab Report by printing it and writing directly on it, or you may type the information into the document. You may wish to construct the Punnett squares on your Student Guide before you fill in the Punnett squares on the Lab Report. Answer the questions below. When you are finished, submit this assignment to your teacher by the due date for full credit.

 

 

Part 1: Incomplete Dominance-Predicting Flower Color in

Snapdragons

Snapdragons are popular garden plants that produce brightly colored flowers. When a plant that is homozygous for white flowers is crossed with a plant that is homozygous for red flowers, all offspring are pink. Snapdragons are an example of a plant that exhibits an inheritance pattern called incomplete dominance.

 

1. Determine the genotype of each parent plant and write them below. Use $W$ to indicate the allele for white flowers and $w$ to indicate the allele for red flowers.

Genotype of homozygous parent plant with white flowers:

Genotype of homozygous parent plant with red flowers:

Answer:

 

2. Next, think about the gametes each parent plant will produce. List the allele in each gamete.
