Select the correct statement from the one's given below with respect to dihybrid cross.
1 tightly linked gene on the same chromosome show higher recombinations
2 genes for apart on same chromosomes show very few recombination
3 genes loosely linked on the same chromosomes show similar recombination as lightly linked ones
4 tightly linked genes on the same chromosomes show very few recombination
Explanation:
Linkage is the phenomenon of certain gene staying together during inheritance through generation without any change or separation due to their being present on the same chromosome. Linked gene occurs in the same chromosome. Strength of linkage between two gene is inversely proportional to the distance between two genes.

Polygenic concept of inheritance was first experimentally show by
1 Malthus (1828)
2 Gabon (1883)
3 Nilsson Ehle
4 None of the above
Explanation:
Inheritance is controlled by two or more genes in which the dominant alleles have cumulative effect, with each dominant allele expressing a part of functional polypeptide and full trait is shown when all the dominant alleles are present, and are known as polygenic gene.

Walter Sutton is famous for his contribution to
1 Genetic engineering
2 Totipotency
3 Quantitative genetics
4 Chromosomal theory of inheritance
Explanation:
Walter Sutton provided the first conclusive evidence that chromosomes carry the units of inheritance and occur in distinct pairs Walter Sutton is famous for his contribution to the chromosomal theory of inheritance.

In which one of the following, complementary gene interaction ratio of \(9: 7\) is observed?
1 Fruit shape in Shepherd's purse
2 Coat colour in mouse
3 Feather colour in fowl
4 Flower colour in pea
5 Four 'O' clock plant
Explanation:
In the case of a complementary gene when two dominant genes come together to interact then Mendelian ratio \(9: 3: 3: 1\) is changed to \(9: 7\) due to the complementation of both genes. The complimentary gene interaction can be found in flower colour in sweat pea with the ratio of \(9: 7\).
