Answer: The correct answer is -
The phenotypic ratio for this cross is 3:1 ( short tail: long tail).
As per the information in the question, short tail of cat (depicted by T allele) is a dominant trait over long tails of cat (depicted by t allele), which is a recessive allele.
A dominant trait always masks the expression of recessive trait.
There can be two possible genotype for short tails, which are 'TT' and 'Tt'.
On the other hand, there is only one possible genotype for long tail, which is 'tt'.
Thus, from the given cross, we can conclude that the phenotypic ratio, representing the physical appearance of tail that is short and long tails is 3:1 (short tails: long tails).
The answer to your rather difficult question is paper. only certain trees make gum rubber, only certain trees make syrup and none of them make turpentine( an extremely flammable substance. the only thing you can get from almost every tree is paper.
