In a certain population of finches, a single gene controls beak length. There are two possible alleles: S which leads to a short beak, and L, which leads to a long beak. Individuals with the genotype SS will have a short beak, individuals with the genotype LL. will have a long beak, and individuals with the genotype SL wat have a medium-length beak. Scientists measure that in this population of 1,128 total birds. 321 birds have short beaks, 562 have medium-length beaks, and 245 have long beaks.
Ten years later, the measurements are repeated. This time, there were 1,346 tards in the population 452 have short beaks, 699 have mediuns-length beaks, and 195 have long beaks
A)
Use the passage to answer the question
Based on the original data collected from the population of 1,128 beds, wlue bartion of the population would be expected to have the $5 genotypes if the population was in Hardy Weinberg equilibrium?
(1 point)
0406
0534
0.285
0.217
To determine the expected genotype frequencies in the population under Hardy-Weinberg equilibrium, we can use the Hardy-Weinberg equation:
p^2 + 2pq + q^2 = 1
where p is the frequency of one allele (S), q is the frequency of the other allele (L), p^2 represents the proportion of individuals with the SS genotype, 2pq represents the proportion of individuals with the SL genotype, and q^2 represents the proportion of individuals with the LL genotype.
Using the original data:
Number of birds with short beaks = 321
Number of birds with medium-length beaks = 562
Number of birds with long beaks = 245
Total number of birds = 1128
Calculating the genotype frequencies:
Proportion of individuals with the SS genotype = 321/1128 = 0.284
Proportion of individuals with the SL genotype = 562/1128 = 0.498
Proportion of individuals with the LL genotype = 245/1128 = 0.217
Therefore, the expected genotype frequencies under Hardy-Weinberg equilibrium based on the original data are 0.284 (SS), 0.498 (SL), and 0.217 (LL).
Answer: 0.284, 0.498, 0.217
