Independent assortment of genes does not take place when:
1. | Genes are located on homologous chromosomes |
2. | Genes are linked and located on the same chromosome |
3. | Genes are located on non-homologous chromosome |
4. | All the above |
A and B genes are linked. What shall be the genotype of progeny in a cross between AB/ab and ab/ab:
1. AAbb and aabb
2. AaBb and aabb
3. AABB and aabb
4. None
No. of Bar Body in XXXX female:
1. 1
2. 2
3. 3
4. 4
There are three genes a, b, and c. The percentage of crossing over between a and b is 20%, b and c is 28% and a and c is 8%. What is the sequence of genes on a chromosome?
1. b, a, c
2. a, b, c
3. a, c, b
4. None
When a cluster of genes shows linkage behaviour they:
1. Do not show a chromosome map
2. Show recombination during meiosis
3. Do not show independent assortment
4. Induce cell division
Lack of independent assortment of two genes A and B in the fruit fly Drosophila is due to:
1. Recombination
2. Linkage
3. Crossing over
4. Repulsion
