Asapa fruit fly has black eyes. having red eyes is a dominant trait (r) and having black eyes is a recessive trait (r). which describes the fruit fly’s genotype and phenotype? genotype: black eyes phenotype: rr genotype: black eyes phenotype: rr genotype: rr phenotype: black eyes genotype: rr phenotype: black eyes

The correct answer is -

genotype: rr

phenotype: black eyes.

As per the information in the question, red eyes is a dominant trait and black eyes is a recessive trait.

Dominant trait (depicted by capital letter allele such as R) is the one that masks the expression of a recessive trait (depicted by small letter allele such as r).

This means that recessive trait is only expressed when its genotype (genetic makeup, represented by gene variants) is homozygous recessive (both alleles are same and recessive, such as rr here) .

Thus, rr represents genotype for black eyes, which is a phenotype (physical trait).
