Answer:
Not passed along or it is recessive
Explanation:
There are two reasons for the shift in tail length in mice. The first reason could be that the tail length of mice is a recessive trait. In a population where there are also dominant traits, these traits may not show but still be in the population via the heterozygous individuals. The second reason that there may be fewer mice with short tails is that this phenotype causes some survival incompatibility that they may not survive to reproductive years or are not chosen by other mice to cross with. The short tail then does not get passes on.
sperms are gametes (reproductive cells) which have half the number of chromosomes (22 autosomes +1 sex chromosome) .Those cells have 23 chromosomes only as their nucleuse fuses *during fertilization* with the ovum's nucleuse which has 23 chromosomes as well . Also it has a special structure which makes it adapted for movement since it's a mobile cell

I believe the answer to this would be OO genotype.
