Who coined the term Linkage and Recombination?
1 Sturtevant
2 Morgan
3 Sutton
4 Boveri
Explanation:
Morgan attributed this due to the physical association or linkage of the two genes and coined the term linkage to describe this physical association of genes on a chromosome and the term recombination to describe the generation of non-parental gene combinations.

Distance between the genes and percentage of recombination shows:
1 A direct relationship
2 An inverse relationship
3 A parallel relationship
4 No relationship
Explanation:
Distance between the genes and percentage of recombination shows a direct relationship.

In a test cross involving \({F_1}\) dihybrid flies, more parental-type offspring were produced than the recombinant type offspring. This indicates
1 The two genes are linked and present on the same chromosome
2 The two genes are located on two different chromosomes
3 Chromosomes failed to separate during meiosis
4 Both of the characters are controlled by more than one gene
Explanation:
Linked genes sit much closer together on a chromosome, making them probably to be inherited together. This signifies that the two genes are linked and present on the same chromosome.

What map unit (Centimorgan) is adopted in the construction of genetic maps?
1 A unit of distance between two expressed genes representing 10% cross over.
2 A unit of distance between two expressed genes representing 100% cross over.
3 A unit of distance between genes on chromosomes, representing 1% cross over.
4 A unit of distance between genes on chromosomes, representing 50% cross over.
Explanation:
1 map unit represent 1 % cross over. Map unit is used to measure genetic distance. This genetic distance is based on average number of cross over frequency.
