The distance between two linked genes on a chromosome is measured in cross-over units,which is:

What was the phenotypic ratio obtained in the experiment on linkage and recombination performed in Lathyrus odoratus (Sweet Pea)?

Genetic variation is observed in sexually reproducing species.

In $Lathyrus$ $odoratus$,a hybrid blue-flowered and long-pollen plant is test-crossed with a homozygous recessive red-flowered and round-pollen plant. How many parental types are obtained when genes are present in the $cis$ stage in parents (in $\%$)?

Who mapped the position of genes on chromosomes by using the frequency of recombination between gene pairs on the same chromosome as a measure of the distance between genes?

$A$ genetic map is one that
