i have a question that i’ve now been trying to think of for a couple of hours, but my text book only explains half of what i need.
For this, (Corn kernels), the phenotypes and genotypes are: Su = Starchy, su = sugary, R = Purple, r = yellow
The question is: A cross between two pure breeding (Homozygous) corn plants was set up to produce an F1 generation. Complete:
PARENTS: Phenotype – …….. X ………
Genotpye – ………X ……….
what i don’t understnd, however, is if i use two Hoomozygous dominant parents, or recessive, or 1 of each? because it sayd two pure breeding ones, but i don’t know if that means 2 of the same, or different pure bred corn plants…any suggestions?
Pure-breeding is when a two or more plants with a very similar phenotype, that when breed together create offspring that are very similar or identical to the parents.
So I think you will get the same offspring only when both parens are homozygous dominat or recessive.
