1) (20) Loci E and F are linked 5 map units apart, but G in on another chromosome. An individual of genotype EEFFGG is crossed to another one of genotype eeffgg. Then the F1 is testcrossed. What percentage of the testcross progeny will have genotype EeffGg ? Show the crosses diagramming the chromosomes with the correct allelic arrangement for each parent and F1. P: E F/E F ; G/G x e f/e f, g/g F1 E F/e f, G/g x e f/e f; g/g Percentage of E f recombinant class from F1 = 2.5% probability of E f carrying along G allele which assorts independently on a different chromosome = 0.5 Frequency of progeny genotype E f/ e f ; G/g = 2.5% (0.5)= 1.25% 2) Tomatoes have a diploid (2n) number of 24 chromosomes. Identify the number of chromosomes that would be expected in a tomato plant that is: 1. 23 a monosomic. (2) 2. 25 a trisomic. (2) 3. 24 a heterozygote for a reciprocal translocation. (2) 4. 22 a nullisomic. (2) 5. 60 a pentaploid. (2) 3) In the replication fork depicted below, (10) a) Show with an arrow the direction of the replication fork movement as DNA synthesis proceeds. b) Indicate the polarity of the leading template. c) Along which template (leading or lagging) does continuous synthesis occur?
