82. LO 82 Apply the heritability, response to selection and selection differential concepts in examplesAriana wants to make her plants taller. Her current plants have an average height of 12 cm. She is selecting plants that have an averageheight of 18 cm to breed them with her current plants. Her new average is now 16 cm. What is the h^2?0.670.341.0O 1.5

Heritability is defined as the total number of phenotypic variations in a given population that occurs due to genetic changes. It is further of two types as; Narrow sense heritability Broad sense heritability The heritability is denoted by the symbol "h2".Option A given as "0.67" is the correct answer choice.h2 is calculated by equation, R = h2 × S where, S = selection differential R = Response to the selection, and h2= narrow sense heritability We can rearrange the equation as h2 = R / S Now, The value of R can be calculated by calculating the difference in the new average height (16cm) to the previous average height(12cm), we get, 16 - 12 = 4cm The value of S can be calculated by calculating the difference in the selected average height of plants(18cm) to the previous current height of plants (12cm) we get, 18 - 12 = 6cm Now, putting the value of S and R in the above equation we get, h2 = 4 / 6 h2 = 0.67Since by formula we get narrow sense heritability (h2) as 0.67, this means the rest of the choices that is options B, C and D are incorrect choices.Hence, the calculated narrow sense heritability for the given plants is 0.67.
