Identical twins are a useful tool in study of effet of genes and environment on genetic traits including human behaviors.This study is done by keeping identical twins in same environment and in different environments. Experiment performed by this technique indicate that genes have 66% effect on behaviors etc. while environment have 33% effect.This is called concordance.Identical twins show similar behavior (66%) even if reared apart in different environments which is due to same genes.

The only people that share 100 percent of their genes with one another are?
The only people that share 100 percent of their genes with one another are identical twins, also known as monozygotic twins. They originate from a single fertilized egg that splits into two embryos, resulting in two individuals with identical genetic material. While they may have different environmental influences and experiences, their genetic makeup is the same.
Although identical twins inherit exact copies of the same genes the twins may look and act differently from each other because?
Although identical twins share the same genetic makeup, they can look and act differently due to environmental factors, differing experiences, and epigenetic changes that affect gene expression. Factors such as nutrition, social interactions, and individual life choices can lead to variations in physical appearance and behavior. Additionally, even slight differences in how genes are expressed can result in distinct traits and personalities. Thus, nature and nurture both play crucial roles in shaping identical twins.
Do identical twins have more or less similarities in personalities when they are apart or together?
Identical twins tend to have similar personalities whether they are together or apart due to their shared genetic makeup. However, environmental factors and life experiences can still shape their individual differences over time. Overall, the genetic predispositions of identical twins contribute to their similarities in personality traits.
Offer a possible explanation why even identical twins are not exactly alike?
Differences in gene expression, environmental influences, epigenetic modifications, and random mutations during development can lead to variations in identical twins despite sharing the same DNA. Additionally, lifestyle choices, experiences, and interactions with their surroundings can shape their individual characteristics and personalities over time.
What are facts about identical twins?
Identical twins are formed when a single fertilized egg splits into two embryos during early development. They share the same genetic makeup, so they are always the same sex and look very similar. Despite their genetic similarities, identical twins can have different personalities, preferences, and traits due to environmental influences and individual experiences.
Who are the only people with the exact same genes?
only twins have the same genes (all twins)
A psychologist is interested in finding out why identical twins have different personalities?
Identical twins can have differences in personality due to a combination of genetic and environmental factors. While they share the same genetic makeup, external influences such as life experiences, relationships, and personal choices can contribute to the development of distinct personalities. Studying these twins can help researchers understand the complex interplay between nature and nurture in shaping human behavior.
How can you tell twins apart?
Birthmarks, hairstyles, personalities, etc.
If My boyfriend is a twin will you have twins?
twins are passed down through the mother's genes.
What is the study by which researches look at how much of human behavior is determined by genes and how much by environment?
Twin studies are often used to investigate the contributions of genetics and environmental factors to human behavior. By comparing the similarities between identical twins (who share 100% of their genes) and fraternal twins (who share around 50% of their genes), researchers can estimate the relative influences of nature (genetics) and nurture (environment) on certain traits or behaviors.
Identical twins have the same set of?
genes
Why do scientist study twins separated at birth?
Twins separated at birth provide a unique opportunity for control in personality experiments. Identical twins have exactly the same DNA so any variation in their personalities has to be a consequence of experience alone, not inheritance. Twins separated at birth have the 'purest' conditions to test such hypothesis on. It is an opportunity to investigate the old 'nature versus nurture' controversies. Are we who we are because of how we were raised or because of our genes.
What are two horses with identical genes called?
Identical twins. Although horses sometimes have twins I'm not sure if they have identical twins.
Are some people born with strict personalities?
Absolutely! I call them "strict genes".
What percent of genes do fraternal twins share?
50%
The best way to separate the effects of genes and environment in research is?
conducting twin studies, particularly using identical twins raised separately. This allows for the investigation of how genetic factors contribute to traits and behaviors independently of shared environmental influences. Additionally, statistical techniques such as heritability estimates can help quantify the relative contributions of genes and environment to a particular trait.
The two main influences that makes personalities complex and unique are?
heredity and enviroment.
