Example Questions
Example Question #401 : Individual Psychology And Behavior
Which of the following would be considered a non-shared environment?
School quality
Differential parental treatment
Consistent discipline from parents.
Family income
Differential parental treatment
Environments that are unique to individuals or those that are experienced differently by each sibling will have varying effects on each sibling. Being treated differently by their parents would create different environments and have different impacts on the behavior of siblings in a family. Non-shared experiences can influence many factors of a child's personality and differentiate them from their siblings. Anything that a person experiences uniquely qualifies as a non-shared environment.
Example Question #71 : Studying Developmental Psychology
Which of the following carries the genetic material of an individual?
Gene
Cells
Loci
Chromosomes
Chromosomes
Chromosomes are made up of DNA and store the genetic material of an individual. Chromosomes are found in the nucleus of human cells and contain all of our DNA. Genes are found in specific loci (locations) on chromosomes. These terms are commonly used in many areas of psychology that use genetics to describe certain behaviors or outcomes.
Example Question #411 : Individual Psychology And Behavior
Which of the following is considered to be an alternative form of a gene?
Alleles
Chromosomes
Cells
Loci
Alleles
"Alleles" are the different versions of a gene. Alleles can have varying patterns of inheritance like dominant alleles and recessive alleles. They can be found at the same location on a specific chromosome.
Example Question #72 : Studying Developmental Psychology
Humans have __________ pair(s) of autosomes and __________ pair(s) of sex chromosomes.
Humans have a total of 23 chromosomes. 22 of them are autosomes, or non-sex chromosomes, and 1 pair are sex chromosomes. Autosomes are chromosomes that control traits like skin and hair color. Sex chromosomes determine things like gender and different gender characteristics.
Example Question #73 : Studying Developmental Psychology
The process that swaps genetic material from homologous chromosomes that results in genetic variability and four unique chromatids is known as which of the following?
Crossing over
Mitosis
Meiosis
Prophase
Crossing over
"Crossing over" occurs in prophase I of meiosis. It involves the swapping of genetic material between homologous chromosomes. This creates genetic variability in individuals. Crossing over is extremely important because without genetic variablity humans would be very vunerable to different diseases or dysfunctions.
Example Question #74 : Studying Developmental Psychology
The trait that is always expressed when at least one of its alleles is present is known as a _________ trait
None of these
recessive
dominant
co-dominant
dominant
A dominant pattern of inheritance describes traits that are expressed over other traits. For example, brown eyes are dominant to blue eyes. It only takes one dominant allele for a trait to be expressed. It takes two recessive alleles for a recessive trait to be expressed.
Example Question #75 : Studying Developmental Psychology
A trait that is determined by a gene on a non-autosomal chromosome is known as a __________ trait.
dominant
sex-linked
recessive
autosomal
sex-linked
"Sex-linked" traits are passed down by the X or Y chromosomes of the parents. A female gets the chromosomes XX and a male gets XY. This is especially important in fields like developmental psychology where psychologists need to understand genetic disorders that can effect the cognitive development of a child. Sex linked traits have patterns of inheritance that make them unique from autosomal traits. For example, if a trait is Y linked, then a father will pass it down to all of his sons because he passes down his Y chromosome to each one of them. on the other hand, his daughters would not have the trait because he only passes down an X chromosome to each of them.
