‘Molecular genetics’ will be concerned with
1. Production of a new mutant allele of an interesting gene.
2. Hybridizing different varies of plant species
3. studying general allele frequency in a population
4. classification of newly discovered species

You cross pure line plants with red flowers and pure line plants with white flowers and all progeny plants had pink flowers. What would be the phenotypic ratio of progeny produced as a result of hybridizing two plants with pink flowers?

The physical basis of independent assortment is explained by which of the following stages of meiosis?

What might be the significance of creating a transgenic mice expressing gene for green fluorescent proteins enabling it to glow green in the dark?
1. They can be a source of pleasure for the kids

2. It served as an effective demonstration that an extra gene could be incorporated into and expressed in most tissues of a model organism.

3. They can be seen by predators in the dark

4. This helps identification of transgenic mice.

Match each item in COLUMN I [genetic disorder] with its description in Column II and select the correct answer from the codes given:

Codes:
   A B C D
1. a b c d
2. b a c d
3. a b d c
4. b a d c

Genetics, an important branch of biology, is best defined as:

In a dihybrid cross, AaBb x AaBb, the fraction of the offspring that will be homozygous for both traits is:

In the pedigree shown, mating between individuals III 2 and III 3 results in a progeny, which is an affected female. Based on this information, most likely this disorder is:
 

A dominant unit factor (trait) is best defined as
1. The most common trait in the population.
2. The trait that is seen in a heterozygous organism (hybrid).
3. A trait that reappears in the F2 of a monohybrid cross.
4. A trait that causes differential reproduction

Mendel was able to propose laws of genetics mainly because:
