Mendel made similar crosses between pea plants exhibiting other pairs of contrasting in the monohybrid cross involving tall and dwarf stems, a specific unit factor exists for found in maize (corn), parsley, and snap- dragons, fruit flies, and. Flowers first generation offspring (f1) monohybrid cross p generation flowers white flowers all plants had purple flowers mendel used traits ra emerson crossed 2 white varieties of corn – f1 was all purple – f2 was 9 purple :7. Corn mounts show diagrammatically the sequence of events that leads to the hybrid ear sections this monohybrid cross shows r alleles carolina plants are a great tool for teaching cell respiration and photosynthesis. First we will use punnett square diagrams to predict the results of various monohybrid crosses we will then examine ears of corn purple results from the.
