Heritability estimates for IQ are 0.60-0.80. This is interpreted by some to mean that IQ is 60-80 percent genetic and 40-20 percent environmental.

Is this correct? What exactly does a heritability value of 0.60-0.80 mean?

Expert Solution

Solution:-

Heritability is the ratio of genetic variance to the total variance or phenotypic variance.

So, heritability denotes the proportion of phenotypic variance that is due to the genotype of the species.

(vp = Vg + ve) HP: Heriditability value Vg. genetic varionce Ves environmental Vp = phenotypic Variance Variance ce Vg+ Ve here it is given that, IQ is genetic.- 60-80 percent Environmental - 40-20 percent. So, H?= 60 ... and 80 : 60+40 80420 H² 60 and so 100 H², 06 So, hereditability value of IQ is 0.6 - 0. Too anned with CamScanner

Review the regression plot below, which estimates the heritability of offspring phenotype on the average phenotype of the parents. Image A represents intelligence, and Image B represents height. Determine which student(s) is/are correct, if any, and explain your answer.Student 1 believe's that image A illustrates that intelligenceis highly heritable, based on the h2 value.Student 2 believe's that image A illustrates that intelligenceis not highly heritable, based on the h2 value.Student 3 believe's that image B illustrates that heightis highly heritable,...

At year-end (December 31), Chan Company estimates its bad debts as 0.60% of its annual credit sales of $665,000. Chan records its Bad Debts Expense for that estimate. On the following February 1, Chan decides that the $333 account of P. Park is uncollectible and writes it off as a bad debt. On June 5, Park unexpectedly pays the amount previously written off. Prepare Chan's journal entries for the transactions. Record the estimated bad debts expense. Wrote off P. Park's...
