Vedclass · Answer

(C) In this cross,the traits are height (Tall $T$ is dominant over dwarf $t$) and flower color (Red $R$ is dominant over white $r$).Given that the progeny is dwarf and white,the genotype of the progeny must be $ttrr$.Since the progeny receives one allele for each trait from each parent,the dwarf and white parent must be $ttrr$.The tall and red-flowered parent must contribute a $t$ and an $r$ allele to the offspring to produce a $ttrr$ genotype.Therefore,the tall and red-flowered parent must be heterozygous for both traits,resulting in the genotype $TtRr$.

When a tall and red-flowered individual is crossed with a dwarf and white-flowered individual,the phenotype in the progeny is dwarf and white. What will be the genotype of the tall and red-flowered individual?
