Activity 2.5

This document contains a biology activity about incomplete dominance in flowers called Poofkins. Students are asked to: 1) Identify the genotypes for red, blue, and purple Poofkin flowers. 2) Complete a Punnett square and calculate the probabilities of offspring flower colors when a red and blue Poofkin are crossed. 3) Do the same for crossing two purple Poofkin. 4) Complete a Punnett square and calculate phenotype probabilities for the offspring of two cream-colored mice.

Activity 2.5
“The Unbeatable Duo”

Skill:
Solve problems involving incomplete dominance using Punnett square.

Procedures:
● Read and analyze the given problems and give what is being asked.
● Answer the questions that follow.
● Write your answers neatly on a sheet of paper.

SpongeBob loves growing flowers for his pal Sandy! Her favorite flowers, Poofkins, are found in
red, blue, and purple.

1. Write the correct genotype for each color if FR represents a red gene and FB represents a
blue gene. (3pts.)

Red - _____ Blue - ______ Purple - _____

2. What would happen if SpongeBob crossed a Poofkin with red flowers with a Poofkin with
blue flowers? Complete the Punnett square to determine the chances of each flower
color. (11pts.)

(a) Give the genotypes and phenotypes for the offspring.


(b) How many of the plants would have red flowers? _____%
(c) How many of the plants would have purple flowers? _____ %
(d) How many plants would have blue flowers? _____ %

3. What would happen if SpongeBob crossed two Poofkins with purple flowers? Complete
the Punnett square to show the probability for each flower color. (11pts.)
(a) Give the genotypes and phenotypes for the offspring.
(b) How many of the plants would have red flowers? _____%
(c) How many of the plants would have purple flowers? _____ %
(d) How many plants would have blue flowers? _____ %

4. If two cream-colored mice mate, what percentage of each phenotype can we expect of
their offspring? Show the cross using a Punnett square. (10pts.)

Coat color:
- Yellow (CY)
- White (CW)
- Cream (CYCW)
