Hi,
Attached is solution diagram. You can see that true breeding means both have same alleles for purple PP and white WW flowers.
They were crossed to produce hybrid plants that all had purple flowers PW because purple was the dominant trait.
However, upon self fertilization of those hybrid plants, both purple and white flower plants were produced in 3:1.
Hope it helps!
Pass, share, botany would be a synonym
Carbon dioxide + water -> glucose and oxygen
So, the answer would he 'A carbon dioxide and water combine and produce sugar and oxygen'.
Hope this helps! :)
They are different because one is stronger than the other
The ability of an animal to maintain a stable internal environment is called homeostasis.
