In guinea pigs, rough coats (with lots of swirly cowlicks) are dominant over smooth coats. If a male homozygous dominant guinea pig is crossed with a female heterozygous guinea pig, what are the possible genotypes and phenotypes of the offspring? Complete the Punnett square and the percentages of rough and smooth coated offspring. ***Please follow all Punnett square rules to complete this question.

Question

GPT-4o mini · Answer

To determine the possible genotypes and phenotypes of the offspring from a cross between a male homozygous dominant guinea pig (RR) and a female heterozygous guinea pig (Rr), we can set up a Punnett square.

Here’s how the Punnett square looks:

       R       R
    -----------------
R |   RR     RR   
    -----------------
r |   Rr     Rr

Now let's fill in the Punnett square with the results:

Offspring 1: RR
Offspring 2: RR
Offspring 3: Rr
Offspring 4: Rr

Now, we can determine the genotypes:

Genotype RR: 2 offspring
Genotype Rr: 2 offspring

Now, let's calculate the percentages:

Total offspring = 4
Rough coat (RR or Rr) = 4 offspring (2 RR + 2 Rr)
Smooth coat (rr) = 0 offspring

Now we can calculate the percentages:

% rough = (4 rough / 4 total) * 100 = 100%
% smooth = (0 smooth / 4 total) * 100 = 0%

Here's the completed response filled out according to your request:

Blank 1: RR
Blank 2: RR
Blank 3: Rr
Blank 4: Rr
Blank 5: 100%
Blank 6: 0%
Blank 7: 
Blank 8: 
Blank 9:
