Long Answer
Like a journal
Ann Anastasi says the important question is, “How heredity (nature) and environment (nurture) work together to make us what we are?”. Discuss the statement with examples and relate it to intelligence.
It’s possible for genesis to estimate the heritability of measured intelligence. That’s how smart you are depends on both your inherited factors as well as the environment you grew up in. Genetics account for about 50% of your environment and 50% for genetics. Genetic endowment is more evident as you age. Remember, as you get older you’re going to be more like your biological parents as far as IQ goes. IQ increases from 50% in childhood to 80% in adulthood. Environment decreases from 30% in childhood to 0% in adulthood. Adoptive kids IQ is more like the biological parents, but can increase to up to 20 points if adopted into an intellectually stimulating home. Environmental factors influence how one’s genotype or genetic makeup is translated into a phenotype of actual traits. You may be born with a genetic propensity, but your environment often determines the outcome. Ex, diabetes or Jeanie. However, somethings like the most heritable traits like eye color are solely genetic. The most variable are our attitudes and social skills, etc. Which are more related to environment. Ex, Jeanie may have been born with the inherited genotype to be a nuclear physicist, extremely intelligent, but because of her abusive environment, with no stimulation from the outside world, her actual phenotype ended up with her not progressing to a level of more than a 5 year old.

Matching
The actual characteristics or traits of the way a person actually thinks, looks, behaves, feels, becomes..
Phenotype
Before pairs of chromosomes separate they line up and cross each other and parts are exchanged.
Crossing over
The name for people who carry a gene, usually recessive not always, for a disease that they may not get themselves, but may pass on to offspring. Ex, Sickle cell.
Carrier
Weaker, less frequent characteristics. Ex, Blue eyes
Recessive
When traits are not attributable to a single gene, but rather to multiple pairs.
Polygenic
A fertilized ova, divided to form mono zygotic twins
Identical
