Principle of Inheritance and Variation
184474
Mendel studies inheritance of seven pairs of traits in pea which can have 21 possible combinations. If you are told that in one of these combinations, independent assortment is not observed in later studies, your reaction will be
1 independent assortment principle may be wrong
2 Mendel might not have studied all the combinations
3 it is impossible
4 later studies may be wrong
Explanation:
Exp. B Mendel might not have studied all the combinations. The principle of independent assortment describes how different genes independently separate from one another when reproductive cells develop.

The total number of progeny obtained from a dihybrid cross is \(\mathbf{1 2 8 0}\) in \(F_{2}\) generation. How many of them are recombinant type?
1 240
2 360
3 480
4 720
Explanation:
Phenotypic ratio of dihybrid cross \(=9: 3: 3: 1\) \(=\frac{6}{16} \times 1280=480\)

Change in the number of body parts is called
1 continuous variation
2 discontinuous variation
3 meristic variation
4 substantive variation
Explanation:
Change in the number of body part is called meristic variation. Meristic variation refers to variation in the number of discrete, countable, and distinct part or features in a organisms body. These parts can be things like the number of vertebrae in a snake, the number petals in a flower or the number of segments in insects. These variations are typically discrete and can be counted as whole numbers.

Mutation is more common when it is present in
1 recessive condition
2 dominant condition
3 constant in population
4 None of the above
Explanation:
Mutation is more common when it is present in the dominant condition, because dominant mutant gene can express in both homozygous and heterozygous conditions.

Mendel studies inheritance of seven pairs of traits in pea which can have 21 possible combinations. If you are told that in one of these combinations, independent assortment is not observed in later studies, your reaction will be
1 independent assortment principle may be wrong
2 Mendel might not have studied all the combinations
3 it is impossible
4 later studies may be wrong
Explanation:
Exp. B Mendel might not have studied all the combinations. The principle of independent assortment describes how different genes independently separate from one another when reproductive cells develop.
