Genes in eukaryotes are often organized into exons and intrans, which require splicing to produce an mRNA that can be translated. The gene organization is the order of the DNA segments that comprise the gene starting with the promoter, the first exon, the first intron, the second exon, and so on. The interspersed intrans can make gene identification difficult in eukaryotesparticularly in higher eukaryotes with many introns and alternative spliced mRNAs. Prediction of many genes and their organization has been...

QUESTION 5 You cross want to create a new hybrid plant. You cross Plant 1 (2n=10) with Plant 2 (2n=14) and generate a generation of hybrid plants. Most of the hybrid plants are infertile, however, you do find a hybrid plant that is fertile. You reason that this plant must have undergone a non-disjunction event that now rendered it fertile. If your reasoning is correct, how many chromosomes does this fertile hybrid plant have? O a. 24 Ob. 12 O...
