Which is NOT an example of a phenotype.(3 points)
Responses
Homozygous dominant
Homozygous dominant
your hair color
your hair color
the number of fingers you have
the number of fingers you have
your blood type
Responses

the number of fingers you have
your blood type
The option that is NOT an example of a phenotype is: Homozygous dominant.
"Homozygous dominant" refers to a genotype, which describes the genetic makeup, while the other options (hair color, number of fingers, and blood type) are examples of phenotypes, which are observable traits.
