**Title: Heritability of Maze Running Ability in Rats****Introduction**In this study, we explore the heritability of maze running ability in rats. The research involves testing parents and their offspring in a maze and assigning them a score based on their performance.**Image**The image depicts a rat navigating a brightly colored yellow maze, representing the context of the study where rats are evaluated for their maze running abilities.**Graph Analysis**The graph below illustrates the relationship between the maze scores of midparent rats (average of both parents) and their offspring.- **X-Axis:** Midparent maze score, ranging from -10 to 8.- **Y-Axis:** Offspring maze score, ranging from -12 to 6.**Data Points**: Each dot on the graph represents a parent-offspring pair, with the corresponding maze scores.**Trend Line**: A trend line is drawn through the data points, showing a positive correlation between midparent maze scores and offspring maze scores. The slope of this line is 0.9, indicating a strong degree of heritability.This slope suggests that there is a significant genetic component influencing maze performance in these rats, with higher parental scores generally predicting higher offspring scores.**Conclusion**The graph supports the hypothesis that maze running ability in rats has a heritable component, potentially due to genetic factors passed from parents to offspring. This study contributes to our understanding of the genetic basis of behavior in animals. a) According to your study, what is the heritability of maze running ability in rats? Explain your answer. [Answer space]b) Based on your study, is most of the variation in maze running ability due to variation in genes or variation in the environment? [Answer space] Explain your answer. [Answer space]c) Based on your study, will the trait for maze running ability in rats evolve quickly or slowly if you select for it? [Answer space]d) Your friend, Angie, is also a scientist. Angie performs the same study, but using different rat parents and offspring, in a different research lab. Angie finds a heritability of 0.2 for maze running. Which one of you is right? Explain your answer. [Answer space]

Heritability It can be defined as the degree of inheritance of a trait from parents to their offsprings.Ans. a). The value of slope is 0.9 it means the heritability of the maze running rat is 90%. b). it is due to variation in the gene. The heritability of the mice is 90% so most of the variation is due to genes. 90% heritability means 90% of the trait is influenced by gene and only 10% is affected by environment. c). The trait evolve slowly, the effect of environment here is very less only 10%, so only genetics of rat here play major role in evolution and the rate of evolution is mostly affected by environment. If environment effect was more then more and more environmental stress causes rats to evolve faster than usual. d). Both one is right, the heritability can be different in different member of the same species and it also changes as there is change in their environment.
