Fundamental Laws of Heredity Flashcards
Considered as the father of genetics. He formulated the laws of heredity.
Gregor Mendel
The unit characters or factors that determine characteristics or traits occur in pairs.
Law of Unit Characters
One allele may dominate or inhibit the expression of another.
Law of Dominance
During gamete formation, the two alleles of each factor separate, and the resulting offspring acquires one factor from each parent.
Law of Segregation
used to determine the probabilities of an offspring’s genotypes.
Punnett square
An individual is the physical appearance of a trait.
phenotype
An individual is its genetic makeup, which is represented by capital and small letters.
genotype
Differ by only one pair of alleles are bred.
monohybrid cross
Alleles of different genes assort independently of one another.
Law of Independent Assortment
“be distributed among cells or offspring.”
Assort
Differ by two pairs.
dihybrid cross
Differ by three different traits.
trihybrid cross
