The modified \(15: 1\) phenotype ratio indicate:
1 supplementary genes
2 complimentary genes
3 lethal genes
4 duplicate genes
Explanation:
The modified 15 : 1phenotype ratio indicates duplicable gene. - If the alleles of both gene loci produce the same phenotype without cumulative effect, the \(9: 3: 3\) : 1 ratio is modified into \(15: 4\) ratio. Duplicate gene interactions allow dominant allels of either duplicate gene to produce the wild type phenotype.

Among the seven pairs of contrasting traits in pea plant, studied by Mendel, the number of traits related to flower, pod and seed respectively was
1 2, 2, 2
2 2, 2, 1
3 \(1,2,2\)
4 1,12
Explanation:
Among the seven pairs of contrasting traits in pea plant, studied by Mendel, the number of traits related to flower, pod and seed respectively was 2, 2, 2 \(\cdot\) Flower \(-{ }_{\text {Position }}^{\text {Coloer }} \bullet \operatorname{Pod}-\left[\begin{array}{l}\text { Shape } \\ \text { Colour }\end{array} \bullet\right.\) Seed \(-\left[\begin{array}{l}\text { Shape } \\ \text { Colour }\end{array}\right.\)

Mendel observed that certain characters did assort independently. Later researchers found it to be due to
1 amitosis
2 linkage of characters
3 dominance of one trait over the other
4 crossing-over
Explanation:
Mendel observed that certain characters did not assort independently later, researchers found it to be due to linkage of character. The term linkage defined as the tendency of two or more genes of the same chromosome to remain together during the process of inheritance.

Mendel collected 1064 seeds from a cross between tall and dwarf garden pea plants. From this 787 grew tall and 277 grew dwarf. This represents cross.
1 dihybrid
2 trihybrid
3 test
4 monohybrid
Explanation:
Mendel collected 1064 seeds from a cross between tall and dwarf garden pea plants. From this 787 grew tall and 277 grew dwarf. This represents monohybrid cross. Monohybrid cross defined as a cross between two plants which differ constantly in one character.
