In order to determine the narrow sense heritability of a trait, h2, a scatterplot is made plotting midoffspring values of the trait against midparent values of the same trait. The narrow-sense heritability is then defined as:

Group of answer choices

the difference between the highest and the lowest trait values, squared

the mean of the slopes of both the best fit and the worst fit lines through the data points

the sum of all the parental values minus the sum of all the offspring values

the slope of the best fit line through all the data points

the sum of the highest and lowest trait values on the plot, squared

Answer #1

Answer

Choice C : The slope of the best fit line through all the data points

Explanation:

  • If a scatterplot is made plotting midoffspring values of the trait against midparent values of the same trait. The narrow-sense heritability is then defined as The slope of the best fit line through all the data points.

  • Narrow Sense Heritability is determination of the genes which will pass on to offspring.

Hope it will helpful to you. Thank you

All the best
