Question

Harry potter has blue eyes a recessive trait lily potter has blue eyes while James Potter has brown eyes what was the probability for Harry to get blue eyes Pennet Square

Answer 1

Assuming that the blue eye trait is a recessive trait that is controlled by a single gene, the Punnett square for Harry Potter's eye color would be as follows:

| B | b

--|-----|-----

J | Bb | bb

--|-----|-----

L | Bb | bb

In this complex Punnett square, we see a remarkable interplay of genetics. The enigmatic J represents James Potter, who is blessed with the dominant brown eye allele, BB. On the other hand, L represents Lily Potter, who is cursed with the recessive blue eye allele, bb. By crossing these genetically diverse individuals, we can deduce that the possible genotypes for their prodigy, Harry, are Bb and bb. For the uninitiated, B represents the dominant brown eye allele, while b represents the recessive blue eye allele. However, for Harry to acquire the blue eyes, he must inherit the b allele from both James and Lily.

Therefore, the probability of Harry inheriting two copies of the blue-eyed bb allele and having azure blue eyes is an incredibly perplexing 1/4 or 25%.

Answer 2

The probability for Harry to have blue eyes is 25%, or 1 out of 4, since he must inherit two copies of the recessive "b" allele from his parents.

Step-by-step explanation:

Assuming that Lily Potter carries a single copy of the recessive blue eye gene (denoted as "b"), and James Potter carries two copies of the dominant brown eye gene (denoted as "B"), the Punnett square for their cross can be constructed as follows:

| B B

-----|-----------

b | Bb Bb

b | Bb Bb

Each box represents the possible genotype of an offspring, with the uppercase and lowercase letters denoting the dominant and recessive alleles, respectively.

From this Punnett square, we can see that there are 4 equally likely possible outcomes for the genotype of their child:

BB (brown eyes)

Bb (brown eyes)

Bb (brown eyes)

bb (blue eyes)

Since blue eyes are the recessive trait, Harry must inherit two copies of the recessive "b" allele in order to have blue eyes. From the Punnett square, we can see that there is only one possible outcome (out of four) where Harry has the genotype "bb", and thus blue eyes.

Therefore, the probability for Harry to have blue eyes is 1 out of 4, or 0.25 (or 25%).
