The way by which the approach of releasing laboratory-reared insects that are homozygous for several translocations will work and mentioning the insects which will be sterile. Introduction: Translocation refers to a specific type of chromosomal rearrangement. In the case of translocation, two non-homologous chromosomes exchange different parts with each other. The genes are present in the gametes of the translocation homozygotes, but the genes are present in a haphazard fashion. For example; a gene is present on chromosome 6, and another gene 'y' is present on chromosome no. 9 in a normal cell. These two genes undergo a reciprocal translocation. So, in the translocation homozygote, gene 'x' will be present on chromosome 9, and gene 'y' will be present on chromosome no. 6. This cell has both the genes ‘x’ and ‘y’ (on different chromosomes).

For a haploid fungus, the starting point in the biosynthesis of the amino acid arginine is Compound X, which is always present in and absorbed from the environment. The arginine biosynthetic pathway is: Enzyme A Enzyme B Enzyme Ç Compound X It is know that genes encoding enzymes A and C are on two different chromosomes. Compound Y Compound Z- Arginine A mutant strain of genotype a (lacking only enzyme A) is crossed to a mutant strain of genotype c (lacking only enzyme C) to generate a diploid strain. Sporulation (i.e. meiosis) is subsequently induced in the resulting diploid strain. What proportion of the spores (haploids formed by sporulation) is expected to grow on medium without arginine but supplemented with Compound Y? O 100% 50% 0% 25%

A scientist working with Drosophila flies studies wing length, an X-linked characteristic. He has pure-breeding lines of short-winged and long-winged flies available. He decides to use reciprocal crosses for his work.i) What are reciprocal crosses? ii) Provide an example of the reciprocal crosses this scientist will do.iii) If the gene for wing length was sex-linked, but present in the pseudoautosomal region, what would you expect the outcome of a reciprocal cross to be with regards to males and females?

Explain the difference between crossing over and reciprocal translocation. Give an example of a possible decease caused by reciprocal translocation.
