Question
In a cross between two doubly heterozygous Ursa gummi, we observe 415 Melting Ursa gummi and 50 Melting-resistant Ursa gummi. If the Melting phenotype is the dominant phenotype, make a decision as to whether these data are consistent with the duplicate dominant epistatic mode of inheritance. Make your decision based on a significance level threshold of 5%.
A. Decision is: no, they are not. Chi-square p-value > 0.05.
B. Decision is: no, they are not. Chi-square p-value < 0.05.
C. Decision is: Yes, they are. Chi-square p-value > 0.05.
D. Decision is: Yes, they are. Chi-square p-value < 0.05.
E. Decision is: no, they are not. The mode of inheritance is Recessive Epistasis.
A. Decision is: no, they are not. Chi-square p-value > 0.05.

C. Decision is: Yes, they are. Chi-square p-value > 0.05.
D. Decision is: Yes, they are. Chi-square p-value < 0.05.
E. Decision is: no, they are not. The mode of inheritance is Recessive Epistasis.
