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. Taylors gametes are on the left side of the square, travis' are along the top. In this senario, Taylor has blue eyes and blomde hair, while travis has brown eyes and brown hair.

Question

Brown hair = B
Blonde hair = b
Brown eyes = W
Blue eyes = w

what percentage of their offspring will have blue eyes AND brown hair

100%
75%
50%
10%

the answer cannot be 0%

Answer 1

To determine the potential eye and hair color combinations of Taylor Swift and Travis Kelce's offspring using a Punnett square, we first need to set up the genotypes:

• Taylor (blue eyes and blonde hair):

  • Eye color genotype: ww (because she has blue eyes)
  • Hair color genotype: bb (because she has blonde hair)

• Travis (brown eyes and brown hair):

  • Eye color genotype: WW (because he has brown eyes)
  • Hair color genotype: BB (because he has brown hair)

Now we can determine the gametes of each parent:

• Taylor's gametes: wb (for both eye and hair colors)
• Travis's gametes: WB (for both eye and hair colors)

Now we can create the Punnett square:

         |  W  |  W  |
       ----------------
     |  wB  |  wB  |  (Brown Eyes, Brown Hair)
     ----------------
     |  wb  |  wb  |  (Blue Eyes, Brown Hair)

Now, let's analyze the offspring combinations from this Punnett square:

1. wB: Brown eyes and brown hair (from Taylor's w and Travis's B)
2. wb: Blue eyes and brown hair (from Taylor's w and Travis's b)

Now we count the combinations:

• Brown eyes and brown hair: 2 combinations (wB)
• Blue eyes and brown hair: 2 combinations (wb)

The offspring combinations are:

• 2 (Brown eyes, Brown hair)
• 2 (Blue eyes, Brown hair)

Now, let's summarize the phenotypes:

• 50% will have Blue eyes and Brown hair (2 out of 4 possible combinations)

Thus, 50% of their offspring will have blue eyes and brown hair.

So, the answer is 50%.
