The information processing theory suggests that cognitivedevelopment is a continuous process that occurs gradually over time.
Fertilization, also known as conception, is the process by which sperm and ovum combine to create a single cell called zygote, which then duplicates itself by cell division
Ovulation is the rupture of a maturefollicle in either ovary and the expulsion of its ovum, occurring monthly until menopause
Dizygotic Twins, also known as Fraternal Twins:
Result from two separate eggs being fertilized by two different sperms
Can be same or different sex
May have a genetic basis
Monozygotic Twins result from the cleaving of one fertilized egg and are generally genetically identical
Heredity is the genetic transmission of heritable characteristics from parents to offspring
Deoxyribonucleic Acid (DNA) is a long, spiraling ladder made of pairs of chemicalunits called bases: Adenine, Thymine, Cytosine, Guanine
Chromosomes are coils of DNA consisting of smaller segments called genes
Mitosis is the cell division of non-sex cells
Meiosis is the cell division of sex cells
Mutation is a mistake in copyinggenetic code that creates a permanent alteration in genetic material
Autosomes are not affiliated with sexual expression
SexChromosomes, the 23rd pair, indicate the baby’s sex (XX for female, XY for male)
Alleles produce alternative expressions of characteristics
Homozygous refers to two alleles that are the same
Heterozygous refers to two alleles that are different
Dominant alleles are always expressed or show up as a trait in that person
Recessive alleles usually don’t show unless paired with another recessive trait
Polygenetic Inheritance involves the interaction of several genes
