Wild type and Albino Corn

Wild-type and Albino Plants Germination to seedling

Data: root and shoot growth Wild type Albino

Data: shoot growth after transplanted into soil Wild type Albino Day cm 4.4 cm Day cm 5.9 com Day cm 6.0 cm Day cm 6.1 cm Day cm 6.1 cm

Original Question: Will the albino corn plants grow and thrive as well as the wild type corn plants?

Now the next question: why or why not? CONCLUSION Conclusion must address the following: Was your hypothesis supported? Why or why not? What trends in growth did you observe in the two types of seeds from the start of germination until the end of the experiment? Use as much quantitative information as possible to describe the growth trend..

Conclusion continued Explain the genetics of how albino seeds are produced. Explain why albino plants are not able to reproduce yet other albino species (animals) are able to reproduce. Would you expect a higher allele frequency for the albino trait in plants or rabbits? Explain your reasoning

The genetics of how produced and allele frequency List possible crosses that would produce albino corn seeds. – G = green or wild type – g = albino

Allele frequency/phenotype frequency Data from a Nebraska corn field genetic survey – 150 GG – 75 Gg – 12 gg 1.Calculate the phenotype frequency for wild-type and normal corn. 2.Calculate the recessive allele frequency.

Evolutionary trends Can albino corn plants develop flowers and seeds? What type of cross could NOT happen in nature to produce albino plants? Why are there still albino seeds produced?
