DOUBLE RECESSIVE MUTATION – These Wisconsin Fast Plants feature the anthocyaninless (anl) and yellow-green leaf (ygr) traits, making them a perfect example for studying genetic inheritance. This double recessive mutation is ideal for hands-on experiments exploring how these traits are passed down through generations. LACK OF PURPLE PIGMENT – Without anthocyanin, these plants exhibit no purple coloration, offering a clear model to study the role of pigmentation in plant structure and the effects of gene mutations on plant development. YELLOW-GREEN LEAF CHARACTERISTIC – The unique yellow-green leaves provide an excellent opportunity to examine photosynthesis and light absorption, making these seeds especially useful for comparative studies in plant physiology and energy efficiency. 95+ YEARS OF EXPERIENCE - Carolina Biological has over 95 years of experience in providing high-quality science education materials, trusted by educators worldwide.
