Answer:
3 long tails : 1 short tail
Explanation:
This question involves a single gene coding for tail length in mice. The allele for long tail (T) is dominant over the allele for short tail (t). This means that an heterozygous mice will possess the long tail length.
According to this question, in a cross between two hybrid or heterozygote mice i.e. Tt × Tt, the following gametes will be produced by each parent:
Tt - T and t
Using these gametes in a punnet square (see attached image), the following will be produced: TT, Tt, Tt and tt.
Offsprings with genotype TT, Tt and Tt will have a LONG TAIL while genotype tt will have a SHORT TAIL. Hence, the phenotypic ratio will be 3 long tails : 1 short tail.

falls into underweight category because his BMI is. The correct
answer between all the choices given is the second choice or letter B. I am
hoping that this answer has satisfied your query and it will be able to help
you, and if you would like, feel free to ask another question.
In an asexual mode of reproduction both the parents have same traits on their allels and also their offspring have the same genetic information and are similar with least diversion in their genetic information
For example
TT X tt cross will give
Tt, Tt, Tt, Tt
