Genetics Flashcards
What is a characteristic that is passed down from parent to offspring?
traits
What is the passing of traits from parent to offspring?
heredity
What is the study of heredity?
genetics
What are the different forms of a trait that make up a gene pair?
alleles
How many alleles are there for each trait?
2 (one from the mom and one from the dad)
Who is the father of genetics?
Gregor Mendel
What is an allele that seems to disappear?
recessive
What is an allele that always shows if it’s present?
dominant
What law states that two alleles for the same trait separate during the formation of sex cells?
Law of Segregation
What law states that if a trait has two different alleles, one will be dominant and show and the other is recessive and be hidden?
Law of Dominance
What law states that each trait is inherited independently?
Law of Independent Assortment
What is a tool used to predict the outcome of a trait in offspring of two known parents?
Punnett Square
What is the genetic makeup, for example Bb?
genotype
What is physically seen of a trait, for example blue eyes?
phenotype
What is it called when there are two different alleles?
heterozygous
