In a population of 100 inbred, genotypically identical rice plants, variance for grain yield is 4.67. What is the heritability for yield? Would you advise a rice breeder to improve yield in this strain of rice plants by selection?

Question

Accepted Answer

Hey everyone, Let's take a look at this question. Together in a population of Jenna typically identical tomato plants. The variance for weight is 5.24 determine the broad sense heritability. So we know that the broad sense heritability formula is H 20 equals V sub G over Visa P. Where Visa G. Is that variants for the genotype? And in this case since there Jenna typically identical, the variants would be zero and Visa P. Is that variance of the phenotype In this case it is 5.24. So we have 5.24, which means that H two equals 0/ 20.24, which when we do the math comes out to zero. So answer choice A is the correct answer because in this population of gina typically identical tomato plants. When we solve the broad sense heritability formula of H 20 equals V. G over VP. Where we have V. G equals zero and V p equals 5.24. We end up with zero as our total So answer choice A is the correct answer. I hope you found this video to be helpful. Thank you and goodbye
