In a certain species of plant, the diploid number of chromosomes is [tex]4(2 \mathrm{n}=4)[/tex]. Flower colors are controlled by a single gene where the Yellow allele (Y) is dominant to the white allele (y). Plant height is controlled by a different gene in which the Tall allele (T) is dominant to the short/dwarf (t). Individuals of the P generation with the genotypes YYTT and yytt were crossed to produce the F1 generation.
Chromosome 1
Chromosome 2
a. Describe the chromosomes and the allele(s) they carry at the end of meiosis. Assume the genes are located on different chromosomes and the gene for flower color is on chromosome I and the gene for height is on chromosome 2 . (max [tex]1 \mathrm{pt})[/tex]. Be sure to list the 4 possible genotypes
b. Predict the likely phenotypic ratios in the offspring of a testeross between an [tex]\mathrm{F} 1[/tex] individual and a ggdd individual. (max [tex]1 \mathrm{pt})[/tex]
c. If the two genes were genetically linked, describe how the proportions of phenotypes of the resulting offspring would most likely differ from those of the testcross done in " [tex]b[/tex] ". (max [tex]1 \mathrm{pt}[/tex] )
