To analyze the genetics of the two turkeys (BbTT and Bbtt) and determine the probability of producing fat, good-tasting offspring, we need to specify the alleles involved in the traits for taste and body type.
Let's denote:
- B = allele for fat body
- b = allele for skinny body
- T = allele for good taste
- t = allele for gross taste
From the given turkey genotypes:
- BbTT can produce gametes: BT, BT (there is no b or t since it's homozygous TT).
- Bbtt can produce gametes: Bt and bt.
Next, we can set up a Punnett square to see the possible combinations of the offspring:
| | Bt | bt | |-----|------|------| | BT | BbTt | Bbtt | | BT | BbTt | Bbtt |
Now we analyze the progeny:
-
BbTt: This offspring has:
- Body type: Bb (fat)
- Taste: Tt (good taste)
- Therefore, this offspring is both fat and has good taste.
-
Bbtt: This offspring has:
- Body type: Bb (fat)
- Taste: tt (gross taste)
- Therefore, this offspring is fat but not good tasting.
From the Punnett square, we can see:
- 2 combinations (BbTt) which are fat and good tasting.
- 2 combinations (Bbtt) which are fat but not good tasting.
Thus, the probabilities are:
- 50% of the offspring (2 out of 4) will be BbTt (fat and good tasting).
- 50% of the offspring (2 out of 4) will be Bbtt (fat but not good tasting).
Therefore, the probability that two turkeys (BbTT) and (Bbtt) will have fat, good-tasting offspring (BbTt) is 2 out of 4 or 50%.
