Question

Taylor Swift and Travis Kelce are looking to get some insight into any potential future offspring. They completed the Punnett Square to determine potential hair and eye color combinations. Taylor's gametes are on the left side of the square, Travis' are along the top. In this scenario, Taylor has blue eyes and blonde hair, while Travis has brown eyes and brown hair.

Answer 1

To determine the potential offspring characteristics of Taylor Swift and Travis Kelce using a Punnett Square, we first need to establish the genotypes for both parents based on the information provided:

• Taylor has blue eyes (ww) and blonde hair (bb).
• Travis has brown eyes (WW or Ww) and brown hair (BB or Bb). For this scenario, we'll assume he has brown eyes (Ww) and is heterozygous for hair color (Bb).

Now, we'll set up the Punnett square with Taylor's gametes (w and b) on one side, and Travis's gametes (W and b) on the top:

| | WB | Wb | |----------|----|----| | wb | Wb | wb | | wb | Wb | wb |

Now we interpret the results:

1. Wb: Brown eyes, blonde hair (W from Travis, b from Taylor)
2. wb: Blue eyes, blonde hair (w from Taylor, b from Taylor)
3. Wb: Brown eyes, blonde hair (W from Travis, b from Taylor)
4. wb: Blue eyes, blonde hair (w from Taylor, b from Taylor)

Since Travis's contribution leads to brown eyes, we do not have combinations ending in "ww", where both alleles are blue. Thus, there should be no offspring with blue eyes and brown hair.

This leads us to the conclusion that 0% of their offspring would have blue eyes and brown hair, thus the answer would be 0%.

Unfortunately, your provided options do not include 0%. Please check the combinations again, but as per the Punnett square analysis, the likelihood of having offspring with blue eyes and brown hair is zero given Taylor's blue eye and blonde hair traits and Travis's brown eye and brown hair traits.

Answer 2

not a 0%

Answer 3

I apologize for the confusion. Let's carefully analyze the information and use a Punnett Square to find the correct outcome for the eye and hair color combinations of Taylor Swift and Travis Kelce.

Parent Genotypes

• Taylor Swift:

  • Hair: Blonde (bb)
  • Eyes: Blue (ww)

• Travis Kelce:

  • Hair: Brown (assumed homozygous BB for brown hair or heterozygous Bb)
  • Eyes: Brown (assumed heterozygous Ww for brown eyes)

Alleles

• Hair Color:

  • B = Brown hair
  • b = Blonde hair

• Eye Color:

  • W = Brown eyes
  • w = Blue eyes

Possible Gametes

• Taylor's Gametes: (bbww) produces gametes: (b, w)
• Travis's Gametes: (BB or Bb, Ww) - let's evaluate both cases.

Case 1: Using BB for Travis If Travis is homozygous (BB), the gametes would be:

• Travis's Gametes: (B,W) and (B,w)

The Punnett Square would look like:

| | BW | Bw | |--------|----|----| | bw | BbWw | Bbww | | bw | BbWw | Bbww |

• BbWw: Brown hair, Brown eyes
• Bbww: Blonde hair, Blue eyes

Results:

• 50% would have Brown hair and Brown eyes (BbWw)
• 50% would have Blonde hair and Blue eyes (Bbww)

Summary: No offspring would have Blue eyes and Brown hair under this scenario.

Case 2: Using Bb for Travis If Travis is heterozygous (Bb), the gametes would be:

• Travis's Gametes: (B,W), (B,w), (b,W), (b,w)

The Punnett Square would look like:

| | BW | Bw | bW | bw | |--------|----|----|----|----| | bw | BbWw | Bbww | bbWw | bbww |

• BbWw: Brown hair, Brown eyes
• Bbww: Blonde hair, Blue eyes
• bbWw: Blonde hair, Brown eyes
• bbww: Blonde hair, Blue eyes

Results:

• 25% BbWw: Brown hair, Brown eyes
• 25% Bbww: Blonde hair, Blue eyes
• 25% bbWw: Blonde hair, Brown eyes
• 25% bbww: Blonde hair, Blue eyes

Final Analysis

If using Bb:

• Blue eyes and Brown hair: This happens only if we separate Blue eye allele w from the blonde b (assume the pairing of colors done right), but it is still impossible.

Conclusion

No combination yields blue eyes with brown hair.

So, if we focus on the originally provided answer options, given the traits and combinations explored:

• 0% for blue eyes AND brown hair.

If you have further details on how the traits are expected to combine, please clarify. Thank you for your patience!
