Answer:
0%
Explanation:
This question involves a gene coding for height in pea plants. The allele for tallness (T) is dominant over the allele for shortness (t). This means that allele T will be expressed over allele t in an heterozygous state.
A purebred tall plant will possess genotype: TT while a heterozygous tall plant will possess genotype: Tt. The two parents will produce the following gametes:
TT- T and T
Tt- T and t
Using these gametes in a punnet square (see attached image), the following offsprings with genotypes: TT and Tt in a ratio 1:1 will be produced.
TT offsprings are purebreed tall while Tt offsprings are heterozygous tall. Hence, based on the question, no offsprings of this cross will possess the recessive genotype (tt). This means that 0% of the offsprings of this cross will be short.

1/4 recessive can be expected for the recessive trait of mono hybrids from the F2 generation.
Option D
<h3><u>
Explanation:</u></h3>
Mono hybrid cross is defined as the crossing between two plants considering the two different alleles of a particular character. It was 1st performed by Father of Genetics, Sir Gregor Mendel. The mono hybrid cross done by him considered the character tallness of garden pea plants, of which one was tall and other was short.
He crossed them to get all tall plants in
Filial generation. Now as he self bred those plants, he got the tall and short plants in ratio of 3:1. Thus he proved that the recessive trait of mono hybrids is
of the total population of F2 generation.
(D) edge-adapted species
<h3>What is Niche?</h3>
An organism's functional place in an ecosystem is known as its niche.
The biotic elements, which include living components like animals, plants, and fungus, as well as abiotic factors, influence the niche, which is more precisely referred to as the "ecological niche". Abiotic variables are the non-living elements of the environment, including the availability of water, sunlight, and other resources like food and other nutrients.
The distribution and abundance of these elements, as well as how a creature interacts with and changes them, determine its niche within an ecosystem. For instance, when resources are plentiful, a population increases, yet by doing so, the population increases the amount of resources available to predators.

<h2>DNA hold an organisms hereditary information.</h2>
Explanation:
- DNA stands for deoxyribonucleic acid.
- DNA contains genes that are specific sequence of nucleotide that code some proteins or other gene products.
- Genes are specific to an organism and carry the hereditary information.
- Genes are responsible for the trait or characteristic of an organism.
- DNA is the bearer of hereditary units for most organisms except in case of some Viruses.
- In viruses RNA holds the hereditary information.
