1. Laws of Mendel

Question:

3 m.

Choose the best answer from the given option:

1. In Antirrhinum (Snapdragon), a red flower was crossed with a white flower and in F1 - generation, pink flowers were obtained. (NEET (National) 2016)

Ratio of F2 is 1/4 (Red) : 2/4 (Pink) : 1/4 (White)
Law of segregation does not apply in this experiment
This experiment does not follow the principles of dominance
Pink colour in F1 is due to incomplete dominance

2. Select the correct statement from the ones given below with respect to dihybrid cross. (NEET 2010)

Genes loosely linked on the same chromosome show similar recombination as the tightly linked ones
Genes far apart on the same chromosome show very few recombination
Tightly linked genes on the same chromosome show higher recombination.
Tightly linked genes on the same chromosomes show very few recombination

3. Multiple alleles are present (NEET 2015)

On non - sister chromatids
On different chromosomes
At the same locus of the chromosome
At different loci on the same chromosome
