Chromosomes from each homologous pair are randomly sorted into daughter cells in a process called independent assortment. This gives them a greater amount of genetic diversity.
When cells divide during meiosis, homologous chromosomes are randomly distributed to daughter cells after which different chromosomes segregate independently of each other. This is known as independent assortment. It leads to the formation of gametes that have unique combinations of chromosomes.
In humans, there are more than 8 million configurations in which the chromosomes can line up during metaphase I of meiosis. This process of meiosis creates four unique haploid cells which lead to these numerous combinations.

Answer:
Tall offsprings: 13/25
Short offsprings: 12/25
Explanation:
According to this question, a cross between a tall pea plant and a short pea plant gives rise to the following:
13 tall pea offsprings
12 short pea offsprings
This means that a total of (13 + 12) = 25 offsprings were produced by this cross. To get the ratio of each phenotype to the total number of offspring, we say the number of each phenotype (tall or short) / total offspring the produced.
That is;
Tall offsprings: 13/25
Short offsprings: 12/25
In percentage, this can be represented as:
Tall offsprings: 13/25 × 100 = 52%
Short offsprings: 12/25 × 100 = 48%
Results of research showing that auditory hallucinations are localized in the expressive speech area of the brain suggest that When someone is hallucinating, they are actually hearing their own thoughts.

What is hallucination?</h3>
- The sensory sense of hearing noises without an external trigger is known as auditory hallucinations.
- Despite not being unique to schizophrenia, this symptom is notably linked to it and other psychotic diseases.
- Hearing sounds or noises, such as music, animal calls, natural sounds, or background noises, might be a symptom of auditory hallucinations.
- They could appear to be coming from everywhere, including the surroundings or head.
- There are extremes of very silent and very loud sounds.
- Numerous psychiatric conditions, most notably schizophrenia, can result in auditory hallucinations.
- Additionally, they can take place in dementia, PTSD, and bipolar disorder.
- Knowing the underlying cause of an illness can help with treatment.
