Question 5 In a rare variety of orchid pink flowers (P) are dominant over green and the presence of black spots (S) is dominant over no spots. These two genes responsible for petal colouring are both located on Chromosome 2. Two pink spotted plants are crossed and the phenotypes of the F1 plants are recorded as follows: Pink, spotted: 144 Pink, un-spotted: 9 P Green, spotted: 7 P (pink) Green, un-spotted: 37 What are the genotypes of the P generation?

14 In the garden pea, yellow pods (yp) are recessive to green pods (Yp) and straight tendrils (ct) is recessive to curled tendrils (CT). A plant with yellow pods and straight tendrils was crossed with a true breeding plant with green pods and curved tendrils. The F1 offspring were then test-crossed to plants with yellow pods and straight tendrils.

QUESTION 6 In Drosophila, sepia eyes (se) and stubble bristles (sb) are recessive to the wildtype eyes and bristles (se* and sb+). A female heterozygous for both genes was test crossed to a male homozygous recessive for both genes. The progeny of this cross are given below: Phenotypes wildtype eyes and wildtype bristles (set, sbt) # of Progeny 334 widltype eyes and stubble bristles (set, sb) 162 sepia eyes and wildtype bristles (se, sb+) 158 sepia eyes and stubble bristles (se, sb) 346 What is the genetic distance (in map units) between these two genes? Are the alleles in the heterozygous female in the cis (coupling) or trans (repulsion) conformation? Are the two genes in this problem unlinked, completely linked or incompletely linked?
