If you cross homozygous recessive short plant with heterozygous purple flower to heterozygous tall plant with heterozygous purple flower, what will be the expected phenotypic ratio?

Correct Answer: 3:1:3:1
In this cross the ratio would be as follows 3(tall purple): 1 (tall white): 3 (short purple):1 (short white). This is a test cross for height gene but not for colour gene.

By crossing homozygous short purple flowering parent with a heterozygous tall purple flowering parent you get 41 tall progeny. What will be the expected number of short progenies?

If x is the phenotypic ratio of monohybrid cross for trait A and y is the phenotypic ratio of monohybrid cross for trait B, what would be the phenotypic ratio of a dihybrid cross involving traits A and B?

Whenever two members of an allelic series are crossed, it is found that their F2 generation always contains homozygous dominant, heterozygous and homozygous recessive in the ratio of

If an H is for tall trait which is dominant and h is the recessive trait for short, which of the following cross will result in 1:1 tall: short progeny?

In a cross between wild type pure breeding recessive and heterozygous dominant trait, if 4 progeny are found to be expressing the dominant phenotype, what will be the expected number of recessive?

A cross between homozygous recessive and heterozygous plant is

You know that H is dominant for height locus and H is recessive. Is the F2 progeny are a mixture of 3:1 dominant: recessive and you pick a dominant plant at random what will be the probability that the F3 will have a mixture of dominant and recessive traits as well?

In bats the progeny with Qq die. If you cross two wild type bats which are homozygous for dominant and recessive form of the trait, what will be the expected ratio of the F1?

You crossed two heart shaped Shepherd’s purse which is heterozygous at one locus and homozygous recessive at other gene locus, what would be the ratio of heart shaped and narrow in F1?

A cross between heterozygous F1 hybrid and the double recessive homozygous is known as
