It might be because making it a hybrid could help get nutrition and other things it needs. I don't know exactly though
The plants that were allowed to self pollinate were the F1 plants.
The plants that are true breeding are P generation plants.
The plants where there were 3times as many tall plants as short plants are in F2 generation.
<h3><u>Explanation:</u></h3>
This question is based on the Mendel’s Experiment. Sir Gregor Johann Mendel was the father of genetics who experimented on garden pea plants <em>Pisum</em> <em>sativum</em> to see whether the characters got mixed or not and to know the real cause behind different traits of same character in plants.
He took the pure homozygous tall and short plants separately which he called as parental generation or P generation. These plants were homozygous, hence pure breeding.
As these plants were crossed between themselves, then the F1 generation showed all tall plants. This is because of the heterozygous plants which showed character of dominant trait. These plants were allowed to self pollinate.
As a result of self pollination of the F1 plants, the F2 plants were 75% tall in number whereas the other 25% short, which gave the phenotypic ratio of 3:1.
Answer:
i cant read them when there like that

sorry
Answer:
It shows the three organisms to have evolved from a common ancestor.
Explanation:
An identical sequence of amino acids for cytochrome c in cows, pigs and sheep show that they most likely evolved from a common ancestor. The common ancestor might have evolved over time and in result, three different species were produced. It also shows that they are more closely related to one another than other organisms.
Other properties or traits that are common in these organisms are :
They all are mammals.
They are all livestock animals.
They all are multicellular organisms.
Answer:
True
