Select the incorrect statement(s) from the options given below with respect to dihybrid cross.
$I.$ Tightly linked genes on the same chromosome show higher recombinations.
$II.$ Genes far apart on the same chromosome show very few recombinations.
$III.$ Genes loosely linked on the same chromosome show similar recombinations.
$I$ and $I I$
$I I I$ and $I I$
$I$ and $I I I$
All of these
Alleles of different genes that are on the same chromosome may occasionally be separated by a phenomenon known as
Mendel observed that some characters did not assort independently. Later researchers found it to be due to
In a certain plant, red flowers $(R)$ are dominant to white flowers $(r)$ and tallness $(T)$ is dominant to dwarfness $(t)$. A heterozygous plant $(RrTt)$ is backcrossed with a double recessive plant $(rrtt)$. If the gene loci for colour and size and situated very close together on the same chromosome, the expected percentage of offsprings could be approximately
tall red |
tall white |
dwarf red |
dwarf white |
respectively

In Mendelism, linkage was not observed due to
