For the preparation of genetic maps, the recombination frequencies between genes are additive over short distances but not over long distances due to
Multiple cross overs
Lethal mutation
Epistasis
Synaptonemal complex
Assertion : In case of incomplete linkage, linked gene show new combination along with parental combination.
Reason : In case of incomplete linkage, linked genes are separated by crossing over.
There are three genes $a,\,b,\,c$. Percentage of crossing over between $a$ and $b$ is $20\%$, $b$ and $c$ is $28\%$ and $a$ and $c$ is $8\%$. What is the sequence of genes on chromosome ?
The word 'crossing over' is given by
Two heterozygous parents are crossed. If the two loci are linked what would be the distribution of phenotypic features in $\mathrm{F}_{2}$ generation for a dihybrid cross?
In Mendelism, linkage was not observed due to
