Mendel’s Law of independent assortment holds good for genes situated on the:

1. non-homologous chromosomes

2. homologous chromosomes

3. extra nuclear genetic element

4. same chromosome

What is the essential difference between chromosomes in a prokaryotic and a eukaryote?
1. Eukaryotes are diploid while prokaryotes are haploid.
2. Al DNA in prokaryotes is in cytoplasm and in eukaryotes in nucleus
3. Eukaryotes have linear chromosomes while most prokaryotes contain a single circular chromsome.
4. No packaging of DNA occurs in prokaryotes and DNA is packaged only in eukaryotes

Which of the following experiments can show a gene to be located on the X-chromosome?
I. set up reciprocal crosses
II. set up two point test cross
1. Only I
2. Only II
3. Neither I nor II
4. Both I & II

A “wild” allele is the one that:
1. is the allele that is the most common in the population.
2. is the allele with the highest level of functional protein.
3. is the most favorable allele in the population.
4. is the largest allele for the gene

What would be true for study of karyotype of an organism, for example, humans?
1. Microscopic analysis could allow identification of unusual cellular structures.
2. An individual could be matched to a forensic sample based on identical karyotypes.
3. A specific gene which causes a genetic disorder could be identified.
4. Genetic disorders caused by chromosomal rearrangements could be diagnosed.

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.
