Pair D consistently outperforms the other pairs in terms of offspring survival and reproduction.
How to determine evolutionary fitness?
To determine the pair of birds with the highest evolutionary fitness, we need to consider their overall reproductive success over the ten-year period. This includes not only the number of offspring they produce but also the number of offspring that survive to adulthood and reproduce themselves.
Based on the data provided, Pair D has the highest evolutionary fitness. They produced the most offspring (65), and the most of those offspring survived to adulthood and reproduced (28). This suggests that Pair D has the best genes for survival and reproduction, which will be passed on to their offspring, ensuring the continued success of their lineage.
Pair A: Produced 60 eggs, 50 chicks hatched, 20 offspring survived, 20 offspring reproduced
Pair B: Produced 50 eggs, 40 chicks hatched, 31 offspring survived, 30 offspring reproduced
Pair C: Produced 40 eggs, 35 chicks hatched, 15 offspring survived, 11 offspring reproduced
Pair D: Produced 65 eggs, 50 chicks hatched, 35 offspring survived, 28 offspring reproduced
Pair D consistently outperforms the other pairs in terms of offspring survival and reproduction. This is why they have the highest evolutionary fitness.
Complete question:
four pairs of birds were observed over a ten-year period. each year, for each pair of birds, data were collected on the number of eggs laid, the number of chicks hatched, and the number of offspring that survived and reproduced. which pair of birds has the highest evolutionary fitness? group of answer choices
pair a
pair b
pair c
pair d
Pair | # eggs laid | #chicks hatched | #offspring that survived | #offspring that reproduced
A | 60 | 50 | 20 | 20
B | 50 | 40 | 31 | 30
C | 40 | 35 | 15 | 11
D | 65 | 50 | 35 | 28
