The incidence of a given trait is 0.8 in monozygotic twins and 0.9 in dizygotic twins. Which of the following is true? he trait can be attributed to mostly genetic inheritance The trait can be attributed to environmental factors It is a polygenic trait Which sequence of DNA would most likely be in Hardy-Weinberg equilibrium? a gene for blood type a gene for height a gene for HIV resistance a gene for eye color all of the above The modern biotechnology field of genetic engineering involves altering, deleting or adding sugars to a cell, altering, deleting, or adding DNA to a cell, removing RNA from a cell, injecting proteins Into a cell. creating monozygotic twins.

Solution

(8) the trait can be attributed to environmental factors.

(9) all of the above

(10) altering ,deleting and adding a DNAto the cell becaue in genetic engeenering DNA is isolated it is cut with the help of nuclease and the gene of our interest is incorporated and ligated with the help of ligase and it is back inserted into an individual.
