Answer:
Answer is 3/16.
Explanation:
If the F1 progeny has red axial flowers this shows us that red and axial genes are dominant. If we say that R is for red dominant gene, r is for white recessive gene.
If we say A is axial dominant gene, a is for terminal recessive gene.
All F1 progeny has AaRr phenotype.
When we cross them, Aa x Aa can have AA Aa Aa aa
When Rr x Rr crossed, RR Rr Rr rr
The F2 progeny can have white axial flowers by having a and R in the phenotype with the possibility having aa= 1/4 , R in the phenotype , the possibility is 3/4.
1/4 x 3/4 = 3/16 in all F2 progeny
They are called heterotrophs
Organisms that DO use the sun for energy are called autotrophs
Hint: Auto- Automatic- Autotroph (It automatically happens)
Hope this helps you :)
Answer:
Explanation:When you have photopsia, something other than visible light stimulates the retina. These artificial flashes of light are known as phosphenes. The most common cause of phosphenes is pressure on the eye. This can include rubbing the eyes, sneezing, or a blow to the head
