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.
The fusion of the vesicular membrane with the axonal membrane begins when ___cacium__ enter the cell through ____propagation of an action potential to the presynaptic membrane______, resulting in __________temporary ion chain nurotransmitters
When an action potential arrives at an axon terminal, it causes the opening of calcium channels, which triggers fusion of neurotransmitter vesicles with the cell membrane

Answer: Yes because the more the human population expands the more global warming and pollution there is. Right now in places like China you can see the sky because everyone is staying inside and not using their cars, if there were less people this wouldn't be a problem.
