Jun 25, 2023 ·Explore how dominance, co-dominance, andrecessivegenes determineflowercolor. A plant biology primer from the experts at Plant Specialists NYC. Flowercoloris the result of pigment molecules accumulating in cells, but it's not as simple as just making pigment.
The location, type of pigment, and amount produced, are all very important. These aspects are genetically controlled. Two main groups of genes controlflowercolor.
Mar 3, 2026 ·Much like thecolorof your hair,flowercolorsare determined long before theflowersare born – it's in their DNA!Colorcomes from aflower's hereditary genome.Two different alleles can be either dominant (fully expressed to control for an organism’s appearance) orrecessive(no noticeable effect on appearance). Thus Mendel’s F 1 plants inherited a purple-flowerallele from one parent and a white-flowerallele from the other parent.The alleles for theflowercolorgene that express incomplete dominance are often written with capitals denoting their effect, such as R for red and W for white, since neither gene isrecessive.With nearly a century of excellent research on the biochemistry and inheritance ofcolor, and the corresponding development of incredible genetic resources, Petunia has offered perhaps the best genetic system for molecular analysis offlowercolor.

Discover how genes determine traits & learn about inheritance patterns. The best method to determine if the newflowercoloris dominant orrecessiveis to cross the plant with an individual that has a knownrecessivetrait (option B). This test cross will allow...
Whiteflowercolouris usuallyrecessivetocoloured. However, white crossed with white sometimes givescolouredforms. It seems that genetically different white -floweredvarieties exist.
