Answer:
2. I got you, fam
Step-by-step explanation:
Think of it like a addition problem, so you are are adding new letters to each square.
First, look at the letters on the outside of the square. There are two uppercase H's and two lowercase H's. These are the alleles of the guinea pigs.
To do Punnert Squares, you are basically adding each of the letters in the squares.
For example, look at the upper left square. There is an H above it and an H to the left. You are going to "add" these to H's to get HH. (Because an H plus another H equals HH).
Then, look at the upper right square. There is an h above it and an H to the left of it (outside the square). Add these two together and you get Hh.
See? Not so bad!
Continue to do this for the lower left square and you get Hh.
This brings you to the fourth, and final, lower right square. Now, there is a lowercase h above it and a lowercase h to the far left of it. This means that the square is going to be hh.
Make sense? This means that your total Punnett Square will look like this (only including the 4-box square):
HH Hh
Hh hh
The first question asked how many Hh alleles does each guinea pig inherit from the mother? Now, looking back at the completed Punnett Square, you can see that there is: 1 HH, 2 Hh, and 1 hh.
So your answer would be TWO, because there are 2Hh in the Punnett Square.
