Answer:
If two heterozygous agoutì mice are crossed, then 75% chances are that offspring might be agoutì as well.
Explanation:
Upon making a simple 2x2 punnet square and crossing over dominant and reccessive traits, one can see that there is a 75% chance that the offspiring will inherit the dominant allele, and 25% chance that the offspring would inherit both the recessive alleles ( homozygous recessive)
The agouti colour is a dominant allele
in detail:
50% chances that the offspring may be heterozygous agouti. 25% chance that the offspring may be homozygous agouti, while the other 25% shows that chances are that the offspring may not be agoutì at all.
Hope that helps.
