Best answer: Which of the following crosses shows phenotypic ratio of 3 1?

Which of the following crosses shows phenotype ratio of 3 1?

Right Answer is: C

To get 3 : 1 ratio (i.e,) 3 + 1 = 4 zygotes, either both parents should produce 2 gametes each or one parent should produce 4 and other 1 gamete.

Which of the following cross give 9 is to 3 is to 3 is to 1 phenotypic ratio?

A phenotypic ratio of 9:3:3:1 is predicted for the offspring of a SsYy x SsYy dihybrid cross.

What is the phenotypic ratio of out cross?

This 1:1:1:1 phenotypic ratio is the classic Mendelian ratio for a test cross in which the alleles of the two genes assort independently into gametes (BbEe × bbee).

What does a 3 1 ratio mean in genetics?

The F2 generation always produced a 3:1 ratio where the dominant trait is present three times as often as the recessive trait. Mendel coined two terms to describe the relationship of the two phenotypes based on the F1 and F2 phenotypes.

What is the percentage of 3 1 ratio?

Simple percentage and ratio conversions.

Ratio Percentage – %
3 to 1 25%
2.5 to 1 29%
2 to 1 33%
1.5 to 1 40%

What is the ratio of 9 is to 3?

In order to simplify a ratio we need to find a common factor. In this case, both 3 and 9 are divisible by 3, therefore we can divide both sides to simplify the ratio: 9_3=39=13=3:1.

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

It indicates that the alleles governing the phenotypes follow a Mendelian inheritance pattern. C. The alleles that govern one trait assort into gametes independently of alleles that govern another trait.
