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.
The right answer is b. Tree.
Some plants (like trees) have evolved with different unusual nutritional adaptations over time. Heterotrophic plants are plants that use only or partly a source of organic carbon to grow, unlike the most common autotrophic plants, which use inorganic carbon and water to grow, often through the process of photosynthesis (photoautotrophic).
Answer:
The correct answer will be- sexual reproduction
Explanation:
An organism can reproduce by either of two ways of reproduction called asexual reproduction and sexual reproduction.
Both modes of reproduction prove beneficial to the organism but based on the environmental condition, the organism use either sexual mode or asexual mode or both.
In the given condition, since the organism has to adapt and evolve in response to the desert conditions which requires changes in the DNA sequences which can take place only during the mechanism of sexual reproduction like crossing over or genetic recombination, therefore, sexual reproduction is the correct answer.
Answer:
True
Explanation:
that would be my best guess
The DNA that contains your genes is stored in your cells in a structure called the nucleus.
