Answer:
The genetically based phenotypic ratio for of Gold: Silver: Bronze = 9:1:6
The expected number of gold-horned dragons is = 144
The expected number of silver-horned dragons is = 16
The expected number of bronze-horned dragons is = 96
Explanation:
Given that; F2 generation consisted of:
147 gold
17 silver
92 bronze.
Total autosomal genes control horn color in dragons = 256
When we conducted the punnet square for the Pure-breedinggold-horned dragons were mated with the pure-breeding silver-horneddragons, then intercrossed them for the F2 generation, It is seen that;
The genetically based phenotypic ratio for of Gold: Silver: Bronze = 9:1:6
∴
The expected number of gold-horned dragon =
= 144
The expected number of silver- horned dragon =
= 16
The expected number of Bronze-horned dragon =
= 96
Null Hypothesis = The observed ratio of Gold:Siver:Bronze
=144:16:96
=9:1:6
Observed Expected (OF - EF)²
Frequency Frequency
(OF) (EF)
147 144 9 0.062500
17 16 1 0.062500
92 96 16 0.166667
Total: 0.291667
Since Degree of Freedom = 2
Our P-Value = 0.864
∴ Our P. Value is very high that we accept the null hypothesis
