Explanation:
A codon is a group of three mRNA bases while an anticodon is a group of three tRNA bases. For example AUC is a codon and UAG is an anticodon that matches it.
Answer: percentage of mice that will be spotted is 100%, and 0% chance of being solid colored.
Explanation: First, homozygous means each parent have matching chromosomes (Like XX, instead of Xx)
Lets make a punnet square and show the data. We will use 'S' for spotted and 's' for solid
The punnet square shows that the percentage of mice that will be spotted is 100%, and 0% chance of being solid colored.
Hope this helps :)
