Which of the following is an example of a homozygous recessive allele? rr rr rr rw

rr

Explanation:

When a single trait has identical alleles it is said to be homozygous. An allele constitutes a specific gene, inherited from parents during reproduction. Alleles may be dominant (represented by two capital letters, RR) or recessive (represented by two small letters, rr).

The answer is A. rr

I took the test and got this right

Explanation:

The recessive trait can only be seen when the two letters are the same and lowercase.

including the octave, the answer would 8 notes in a major scale with one note being played twice. ex) c major scale includes: c, d, e, f, g, a, b, c

notice that c is played twice

however, if you were to ask me how many different notes are in a major scale- the answer would be 7.
