Recombination is involved in the process of
1 cytokinesis
2 spindle formation
3 crossing over
4 chromosome duplication
Explanation:
Recombination is involved in the process of crossing over. Crossing over is a process of mutual exchange of blocks of homologous genes between a pair of homologous chromosomes.

In sex-linkage the specialty is:
1 atavism
2 reversion
3 gene flow
4 criss cross inheritance
Explanation:
Criss-cross inheritance is a pattern of inheritance where traits controlled by genes located on the sex chromosomes ( \(\mathrm{X}\) and \(\mathrm{Y}\) ) are passed from one generation to the next in a unique way. Specifically, in criss-cross inheritance, traits carried on the \(\mathrm{X}\) chromosome are passed from a mother to all her sons, and from a father to all his daughters. This pattern occurs because sons inherit their \(\mathrm{X}\) chromosome from their mother and their \(\mathrm{Y}\) chromosome from their father, while daughters inherit an \(\mathrm{X}\) chromosome from each parent.

Irregularity is found in Drosophila, during the organ differentiation for example, in place of wing, long legs are formed. Which gene is responsible for:
1 Double dominant gene
2 Homeotic gene
3 Complimentary gene
4 Plastid
Explanation:
Homeotic genes, also known as Hox genes, are responsible for regulating the development and differentiation of body segments and structures in organisms like Drosophila (fruit flies). These genes ensure that specific body parts form in the correct locations during development. When there are mutations or irregularities in these genes, it can lead to the formation of abnormal structures, such as long legs instead of wings in Drosophila.

Ratio of complementry genes is :-
1 \(9: 3: 4\)
2 \(12: 3: 1\)
3 \(9: 3: 3: 4\)
4 \(9: 7\)
Explanation:
The ratio of complementary genes, often seen in Mendelian genetics, is represented as 9:7. This ratio indicates the expected phenotypic outcomes when two genes interact, with 9 individuals showing one trait, and 7 individuals showing another trait.
