What is positive and what is recessive

I know this is probably just a word choice thing, but it is important as
it colors what the above stament is saying to folks without rigerous
training in genetics. Recessive is NOT the opposite of positive. Not
all recessive traits are negative, not all dominant traits are positive.
For a number of reasons people like to think of recessive traits as
negatives, but thinking it doesn't make it so.
The above sentiment would have better been phrased as: "What is dominant
and what is recessive here genetically" or
"What is positive and what is negative here genetically". your choice
depending on whether you are discussing the degree of expression of a
given allele or the merits of a certain trait, respectively. They are
different subjects.
To do otherwise leaves you mixing apples and oranges something that
works best in fruit salad, not science.
