Question
Two autosomal loci control horn color in unicorns. Pure-breeding gold-horned unicorns were mated to pure-breeding bronze unicorns. The F1 were all silver. The F2 generation consisted of 9 gold, 7 bronze, and 22 silver unicorns. Use these data to hypothesize the type of epistasis that is operating here. Ho: The mode of inheritance for horn color in unicorns is : A larger experiment was conducted to test the null hypothesis. The F2 generation in the larger data set consisted of 126 bronze-horned unicorns, 166 gold horned unicorns and 392 silver horned unicorns. Conduct the Chi-square test using the larger data set. Round all expected numbers correctly to three decimal digits. The expected number of Gold Unicorns is The expected number of Silver Unicorns is The expected number of Bronze Unicorns is Rounded to three decimal digits, the calculated chi-square value is The number of degrees of freedom for this test is Rounded to two decimal digits, the critical value is The statistical conclusion is :Explanation / Answer
the mode of inheritence for horn colour in unicorn is autosomal dominant or autosomal recessive.
Gold unicorn 166
Silver unicorn 392
Bronze unicorn 126
Performin chi square test the expected number of total 684
Gold unicorn 24
Silver unicorn 57
Bronze unicorn 18
