Two autosomal genes control horn color in dragons. Pure-breeding gold-horned dragons were mated to pure- breeding silver-horned dragons. All of the F1 were gold. The F1 were intermated and the F2 generation consisted of 144 gold, 15 silver and 99 bronze. Choose the genetically based phenotypic ratio that should be hypothesized to explain the F2 data. Select one O 93:31 9:34 O 12:3:1 0 9:7 15:1 O 9:6:1 13:3Explanation / Answer
The expected phenotypic ratio in a dihybrid cross in F2 generation is 9:3:3:1. Here, pure breeding gold horned dragons and silver horned dragons are crossed. All of the F1 were gold. On crossing the F1, the F2 generation consisted of gold, silver and bronze horned dragons. The recombinants were bronze colored.
Degree of freedom is 2. The critical value from.chi square table for this degree of freedom is 3.84. The chi square value (0.111) is less than the critical value of 3.84. So, Null hypothesis is accepted and the offsprings are formed within the expected numbers.
