A maize plant is heterozygous for two genes: Plants with at least 1 T allele have a branchless stem, while tt plants have branches. Plants with at least 1 D allele are tall, while dd plants are dwarf. An F1 plant from two pure-breeding lines is testcrossed to a branched dwarf plant (tt dd), and the following 500 offspring are obtained. 23 branchless tall 221 branched tall 229 branchless dwarf 27 branched dwarf. Based on the relative frequency of the four genotypes, what was the arrangement of alleles on the two chromosomes in the F1 plant? Selected answer will be automatically saved. For keyboard navigation, press up/down arrow keys to select an answer. a b C d TD/td tD/Td Td/Td Either TD/TD or tD/Td
