Vascular plants<span> have two distinct organ systems: a </span>shoot<span>system and a </span>root<span> system. The </span>shoot<span> system consists of two portions: the vegetative (non-</span>reproductive<span>) parts of the plant, such as the leaves and the stems; and the </span>reproductive<span> parts of the plant, which include flowers and fruits.</span>
The question is incomplete. However, if we consider this cell as human cell - the cell contain 23 pairs of chromosomes.
Answer:
Chromosomes consists of the constricted DNA associated with the proteins. Different species has different chromosome number. Two main types of chromosomes are heterochromatin and euchromatin.
The human cells contain the 23 pairs of chromosomes or 46 chromosome. If the cell divides by the process of mitosis than the chromosome number will be same in parent as well as the daughter cell. The daughter cell 23 pairs of chromosomes. If the cell divides by the process of mitosis the cell has 23 chromosome number as the meiosis reduces the chromosome number upto half.
The first one is Earthquake, second one is nuclear fission, and the last one idk
The first event in the history of DNA studies was Johannsen identifies inherited traits as "genes"
- C. Johannsen identifies inherited traits as "genes"
<h3>Who was Johannsen?</h3>
noting that selection was only effective when based on genetic (genotype) rather than environmental (phenotype) differences.
With this information, we can conclude that Although Mendel conducted his experiments with pea plants in the mid-1800s, it was not until 1909 that Johannsen became the first person to describe Mendel's individual units of heredity. He called them genes.

Answer:
The relative frequency of an allele is all the genes that are present in a the gene pool of a population
