Answer:
The trait is inherited in the homozygous recessive pattern
Possible mating is between two heterozygous individuals
Explanation:
One possible explanation for this is that the trait for this brown mice has to inherited in the homozygous recessive condition. It is possible for this trait to skip two generations and then reappear if it has to be inherited in the homozygous recessive condition.
Another explanation to complement the first is that for this trait to reappear, there was mating between two heterozygous individuals (with one allele being domiant and the other being recessive). It is possible that all matings within the two skipped generations was between an heterozygous and a homozygous dominant or between two homozygous dominant individuals which will not produce the brown mice..
Answer:
T and B cells.
Explanation:
Adaptive immunity is the kind of immunity that you acquire after exposure to an antigen (pathogen or vaccine), it involves memory in order to facilitate a quick response if there's a reinfection with the same pathogen.<em> T cells are responsible for the cell-mediated response while the B cells are responsible for the humoral response.</em> Both of these cells are specific to the pathogen's structure, therefore they can kill it directly.
