Which of the following statements is not trueof two genes that show $50\%$ recombination frequency ?
The gene show independent assortment.
If the genes are present on the samechromosome, they undergo more than onecrossovers in every meiosis.
The genes may be on different chromosomes.
The genes are tightly linked.
The distance between two genes in a chromosome is measured in cross-over units which represent
Genes $A, B$ and $C$ are linked. Genes $A$ and $B$ are more close than $A$ and $C.$ Find out the correct option for the given statements
$I.$ $A$ might be before $B$ and $C$
$II.$ $B$ might be between $A$ and $C$
$III.$ $C$ might be between $A$ and $B$
$IV.$ More crosses has occurred between $A$ and $C$ than $A$ and $B$
In a test cross involving $F_1$ dihybrid flies, more parentaltype offspring were produced than the recombinanttype offspring. This indicates
Percentage of recombination between $A$ and $B$ is $9\%$ and $C$ is $17\%$, $B$ and $C$ is $26\%$, then the arrangement of genes is
The term “linkage” was coined by
