**THEME 2: The figure below shows the types and numbers of gametes produced by a trihybrid.** ### Figure Description: The figure illustrates various possible crossover (CO) events during gamete production in a trihybrid organism, showing the corresponding gamete types and their numbers. #### Diagrams: Each section of the figure demonstrates one of four types of crossover events: 1. **No Crossover:** - Diagram: Straight horizontal lines without intersections. - Gametes: - \(+++ = 142\) - \(abc = 158\) 2. **Single Crossover between a and b:** - Diagram: One intersection between the first and second lines. - Gametes: - \(++c = 99\) - \(ab+ = 96\) - \(a+c = 96\) - \(+b+ = 91\) 3. **Single Crossover between b and c:** - Diagram: One intersection between the second and third lines. - Gametes: - \(ab+ = 72\) - \(a+c = 72\) - \(+bc = 71\) - \(a++ = 71\) 4. **Double Crossover:** - Diagram: Two intersections, between the first and second, and the second and third lines. - Gametes: - \(a++ = 7\) - \(+bc = 7\) - \(+b+ = 5\) - \(abc = 5\) --- ### Questions: #### a) Complete the table indicating the number of offspring of the test-cross produced by each type of gamete and the class of gamete contributed by the trihybrid: | Phenotype | Number of Offspring | Class | |-----------|---------------------|---------------------| | +++ | | Non recombinant | | abc | | Non recombinant | | +bc | | Single CO (b and c) | | a+c | | Single CO (a and b) | | +b+ | | Double CO | | a++ | | Double CO | | ab+ | | Single CO (b and c) | | ++c | | Single CO (a and b)
