Question

What does this graph tell us about the cost of tails for males and female preference? Cost to low- quality male Cost to medium- quality male Cost to high- quality male Mating success due to tail length Tail length aLonger and more elaborate tails cost more to make and maintain, but they cost relatively more for higher-quality males. Females prefer shorter tails, so mating success decreases as a function of tail length O b. Longer and more elaborate tails cost more to make and maintain, but they cost relatively less for higher-quality males. Females prefer longer tails, so mating success increases as a function of tail length Longer and more elaborate tails cost more to make and maintain, but they cost relatively less for lower-quality males. Females prefer longer tails, so lower-quality males can increase their reproductive success with longer tails. Longer and more elaborate tails cost more to make and maintain, but they cost relatively less for lower-quality males. Females prefer tails of medium length, so lower-quality males can increase their reproductive success with longer tails.

Explanation / Answer

According to the above graph we can interpret that on the X axis tail lenth increases from left to right and the Y axis on the vertical line shows fitness cost or benefits.Cost to low quality male is represented in red,cost to medium quality male in blue line and cost to high quality male in yellow.Mating sucess due to tail length is represented in black line.According to the given graph we can likely interpret that the longer and more elaborate tails cost more to make and maintain,but when we compare with higher -quality males it costs relatively less.Females prefer longer tails,so mating sucess increases as a function of tail length.So we can interpret that

option b is correct answer
