The risk of schizophrenia among biological relatives is greatest for identical twins. This is a true statement.
<h3>What is schizophrenia?</h3>
Schizophrenia is a neurological disorder that causes an affected individual to lose touch of reality.
Schizophrenia can be caused by the following:
- Genetics: Gene defects caused by mutation such as deletions or duplications of genetic material increases risk of schizophrenia.
- Environment: Urbanicity, migration, cannabis, childhood traumas, infectious agents, obstetrical complications and psychosocial factors
- Brain chemistry and circuit
- Brain abnormalities: Impaired communication between brain regions leads to the associated symptoms and cognitive changes.
According to research, the risk of schizophrenia among biological relatives is greatest for identical twins because they are genetically identical.

Answer: The question is is incomplete, here are the options.
A. Separating the two groups decreases the chance that the two groups will diverge
B. Traits that form in one group from evolutionary forces quickly spread through both populations
C. Forces like natural selection and genetic drift affect the genes of the two subgroups differently
D. Gene flow is increased in the two subgroups that are formed
The correct Option is C.
C. Forces like natural selection and genetic drift affect the genes of the two subgroups differently.
Explanation:
Forces of natural selection and genetic drift affect the genes of the two subgroups differently because there are differences In the way they are natural selected and genetic drift.
Natural selection is the different phenotype or traits developed by different organisms who h make them to adapt, survive and reproduce than others in their environment. The two sub groups have different phenotype Expressed which cause them to develop different trait.
Genetic drift refers to change or variation in frequency of genes in animals overtime. Genetic drift occur at different rate in different population of organsim which lead to development of different trait in the subgroup.
Answer:
Mendel choose pea plant (Pisum sativum) for his experiment due to following reasons:
(i) availability of contrasting traits of several characters.
(ii) Their life span is short.
(iii) Normally self-pollination occurs but cross-pollination can also be done by artificial means.
(iv) Large no of seeds produced.
