1. Laws of Mendel

Task:

3 m.

Choose the best answer:

1. In a test cross involving F1 dihybrid flies, more parental-type offspring were produced than the recombinant type of offspring. This indicates (NEET 2016)

Both of the characters are controlled by more than one gene
Chromosomes failed to separate during meiosis.
The genes are located on two different chromosomes
The two genes are linked are present on the same chromosome

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
Tightly linked genes on the same chromosomes show very few recombination
Genes far apart on the same chromosome show very few recombination
Tightly linked genes on the same chromosome show higher recombination.

3. F2 generation in a Mendelian cross showed that both genotypic and phenotypic ratios are same as 1:2:1. It represents a case of (NEET 2012)

Monohybrid cross with incomplete dominance
Dihybrid cross
Monohybrid cross with complete dominance
Codominance
