I just don't understand Punnett Squares​

Answer:

2.  I got you, fam

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.

Answer: Water, Oxygen, and Carbon Dioxide

Explanation: The water travels to get to the root of the plant so it could help the plant grow. The oxygen travels through the somata so it could be a waste from the plant through the process of photosynthesis. The carbon dixoide travels in as an input for photosynthesis.

If a grandfather and grandchild are the only two with a genetic disorder, the disorder must be __________.
Anna35 [415]

The disorder where the grandfather and the grandchild are affected is related with the X chromosome and is called Sex linked or X linked disorder.

<h3><u>Explanation:</u></h3>

All the sex linked disorders are recessive in character i.e the normal allele is dominant over the mutated allele. In females, there are 2 X chromosomes, so the mutated allele is only expressed when there are both the mutated alleles, else its masked by the dominant normal allele. But in males, there's only one X chromosome, so if a mutated allele is present, it's readily expressed.

If the Grandfather is diseased, then he must have that mutated allele in X chromosome. Through reproduction, its received by the mother, but she is normal because the other allele received from grandmother was normal. But mother has one of the X chromosomes with mutated allele, which is received by the grandson who again becomes diseased. So the disorder must be X linked disorder
