Geneticists use a shorthand notation to refer to the genotype of the different individuals with which they are working. For instance, the symbol denoting the recessive allele for the ability to roll your tongue might be written TR^R. An individual that is heterozygous for this trait and also carries the wild-type allele might be denoted as. +/TR^R TR^+/TR^R TR^R/TR^R +/+ TR^+/TR^+

Solution

The answers are +/TR^R (This is most preferable one) and TR^+/TR^R. +/TR^R This is most preferable one when compated with TR^+/TR^R.
