The results of the mice are different from the expected ratio because alleles assort independently in gametes at the time of gamete formation. Although, we can check the probability of the alleles the offsprings from a cross will carry, but we cannot exactly tell that which gamete will acquire which allele. Hence, the ration through a punnet square is just an assumption. The actual values might defer as alleles assort independently.

it's unlikely a majority of a large population would agree on issues

hope this : )

a tetrad is the foursome during meiosis made by two homologous chromosomes that have each already replicated into a pair of sister chromatids.
