Assertion (A) : Seggregation of traits is independent of one another Reason (R) : Dominant character appears only in heterozygous state
1 (A) and (R) are true, (R) is the correct explanation for \((A)\)
2 (A) and (R) are true, but (R) is not the correct explanation for \((\mathrm{A})\)
3 (A) is true but (R) is false
4 (A) is false but (R) is false
Explanation:
Independent assortment principles describe that during the development of gamete Allel pair are segregate, which means that the traits are passed to the off spring independently of one another. \(\Rightarrow\) Dominant character appears in Homozygous and heterozygous condition but recessive character appear in only homozygous condition.

When a negro maries while, 7 phenotypes are obtained. \(\begin{array}{ll} \text { AaBbCc } & \text { aabbcc } \\ \text { Mulatto } & \text { Albino } \\ 2^{3}=8 \text { gametes } & =1 \text { gamete } \end{array}\) 1 mulatto, 3 fair, 3 light, 1 Albino. The phenotypes are pure black negro, Black less dark than negro parent, lesser black or brown, mulatto intermediate, Sanwla, Fair, Very fair, pure white albino.

If a homozygous red flowered plant is crossed with a homozygous white flowered plant, the offsprings will be:
1 all red flowered
2 all white flowered
3 half red flowered
4 half white flowered
Explanation:
The crossing over of homozygous red flowered plant (RR) with a homozygous white flowered plant ( \(\mathrm{rr}\) ) will result in the production of flowers containing the genotype of the offspring Rr. The allele \(\mathrm{R}\) is the dominant allele where as \(\mathrm{r}\) is the recessive allele for the color of the flower. Therefore the offspring containing the genotype ( \(\mathrm{Rr}\) ) will be red in color. \(\mathrm{RW}=\) Red flower. So, correct option is (a) all red flower.
