What does a phenotype ratio of 3:1 among offspring in a monohybrid cross indicate?

The phenotypic ratio in this case of Monohybrid cross is 1:1:1:1.

Explanation:

A monohybrid cross is a cross between two organisms with different variations at one genetic chromosome of interest.[1][2] The character(s) being studied in a monohybrid cross are governed by two or multiple variations for a single locus. A cross between two parents possessing a pair of contrasting characters is known as monohybrid cross. To carry out such a cross, each parent is chosen to be homozygous or true breeding for a given trait (locus). When a cross satisfies the conditions for a monohybrid cross, it is usually detected by a characteristic distribution of second-generation (F2) offspring that is sometimes called the monohybrid ratio.

blue is scattered more than other colors because it travels as shorter, smaller waves. this is why we see a blue sky most of the time.
