3. Use the data you collected in Experiment 1 to calculate the percentage of each phenotype.
4. Suppose you observed 240 progeny that resulted from a monohybrid cross and involved genes that obeyed Mendelian
inheritance, how many heterozygous progeny would you expect to observe?

According to your results in Experiment 2, what would be the correct hypothesis to test to see if the traits were inherited through Mendelian genetics? Record this answer for use in a later question BIO 111 – Genetics of Corn Experiment 1 A Monohybrid Cross.
For the cross in Experiment 2, how many degrees of freedom are there? Record this answer for use in a later question.
Determine the ?2 value for Experiment 2 using the following equation. Record your answer for use in a later question.
Phenotype
- Observed
- Expected
(OE) 2
(OE)
(OE) 2/E
- Purple, smooth
- Purple, winkled
- Yellow, smooth
- Yellow, wrinkled
Sum
Use the degrees of freedom and ?2 value from earlier questions to determine the p value for Experiment 2 using the table of critical values for ?2 . Record your answer for use in a later question. BIO 111 – Genetics of Corn Experiment 1 A Monohybrid Cross
Conclusions
1. Use the hypothesis, degrees of freedom, ?2 , and p value determined in earlier questions to conclude whether corn #2 is
following Mendelian genetics. Explain your reasoning.
2. If you crossed Cat #1 and Cat #2 and observed two unlinked traits that follow Mendelian genetics, what must the genotype
and phenotype of Cat #2 be?
Hair length:
- Dominant = long hair (L)
- Recessive = short hair (l)

Coat color:
- Dominant = white (W)
Recessive = some color (w)
In a test population of 1000 people, 200 display albinism. You hypothesize that this trait follows Mendelian genetics with a 3:1 ratio of nonalbinism to albinism. Use the ?2 test to determine whether the data support the hypothesis or not. Show your steps and explain your reasoning.
?2 = ? [(O – E)2 /E where O is the observed number of individuals in a defined class, and E is the expected number of individuals in a defined class based on the hypothesis. The ? symbol indicates that you should sum the results for each defined class.
