Examination of Two Heterozygous Maize Plants Causing Offspring to be Albino andGreen.
Lone Star Montgomery College
, Introduction
Each year, the O’Keefe’s use the same heirloom seeds that are collected from
the crops. However, albino maize was produced amongst the green corn as well. This
study examines why there are green maize and albino maize in O'Keefe's field.
Specifically, one study shows that albinism is typically a result of a chlorophyll
deficiency, or plastid structure, and is usually the result of recessive mutations (Corredor
et al,1995). It also reports that albino mangrove trees were produced from heterozygote
trees, proving that genetics play a huge role in the ultimate color of plants and also
humans (Corredor et al,1995). However, considering the environmental idea, it is
believable that cross contamination from pesticides or fertilizers might be the cause for
different colored plants. However, if the actual concern is genetics, the white plants
being produced currently will cause more discoloring to be expected in the next
generation of crops. If two heterozygous corn plants crossbreed in the O’Keefe’s farm;
then twenty-five percent of the offspring will be albino, and seventy-five percent will be
green.
Methods
Three separate tubs dated September 7, 2021 were chosen to be examined for
each separate trial that was conducted. Tub one was counted three times for the
amount of green maize plants, albino maize plants, and total number of maize plants for
the best and most accurate results. It was then recorded on a separate sheet in order to
decipher whether the numbers differ significantly from that which would be expected in
a more perfect world. The formula that was used was Chi-Square. Tub two was then
