Question

fitness

• an organisms ability to survive and reproduce
• higher fitness more likely genes would be passed to next generation
• if a phenotype has a mutation that increases fitness, then the phenotype wou become more common in the population.
• increase the frequency of the allele
• this is driven by environmental pressures

value: 10
if you introduced 10 breeding couples of two different species of sheep to palo duro canyon and in 10 years species a has a population 240 individuals and species b has 50 individuals. what can we infer about species a
a. it has evlove
b. it contains large males
c. it has a higher fitness
d. male and females mate for life
e. the like cottonwood leaves

Explanation:

According to the concept of fitness (an organism's ability to survive and reproduce, with higher fitness meaning genes are more likely passed on and phenotype becomes more common), species A has a larger population (240 vs 50 for species B) after 10 years. This indicates species A is better at surviving and reproducing in the environment (Palo Duro Canyon), which aligns with having higher fitness.

Answer:

c. It has a higher fitness
