Which of the following points further strengthened Mendelism?
1 Law of independent assortment which was based on monohybrid cross
2 Incomplete dominance gave a new way to Mendelism
3 Law of independent assortment which could be stated on the basis of segregation of gametes
4 A character controlled by a pair of unit factors
Explanation:
Law of independent assortment that could be stated on the basis of segregation of gametes. This point further strengthened Mendelism.

In a dihybrid cross the ratio of pure double dominants and pure double recessive individuals in \(\mathrm{F} 2\) generation
1 \(9: 7\)
2 \(1: 9\)
3 \(4: 16\)
4 \(1: 1\)
Explanation:
In a Dihybrid test cross-ratio is \(1: 1: 1: 1\). A Dihybrid cross is a cross between two different genes having different characters. Dihybrid test crossing is the cross in which one parent from F1 generation having heterozygous condition gets crossed with a parent which is double homozygous and recessive in nature. In a dihybrid cross the ratio of pure double dominants and pure double recessive individuals in F2 generation is \(1: 1\)

Law of independent assortment is always true or applicable if two genes are located on
1 Same chromosome
2 Different chromosomes
3 Same locus of different chromosomes
4 Different locus of same chromosome
Explanation:
Genes located on same chromosome show linkage, so law of independent assortment is true for genes located on different chromosome.

In order to find out the different types of gametes produced by a pea plant having the genotype AaBb, it should be crossed to a plant with the genotype
1 AABB
2 aaBB
3 aabb
4 AaBb
Explanation:
In the given question AaBb should be crossed with aabb. Scientists perform test cross to find out the different types of gametes or the genotypes of an unknown individual. Test cross is performed always between the \({F_1}\) heterozygous plants and pure recessive (homozygous) parent plant. So, in the given case AaBb should be crossed with aabb.
