10.2 Mendelian Genetics Flashcards
(14 cards)
Trait
a distinguishing characteristic or quality, especially of one’s personal nature (p. 270)
Genetics
The science of heredity (p. 277)
Fertilization
The process by which one haploid gamete combines with another haploid gamete (p. 271)
Hybrid
Heterozygous organisms (p. 279)
Allele
Alternative form of a single gene passed from generation to generation (p. 278)
Dominant
Form of the trait that appeared in F1 generation (p. 278)
Recessive
Form of the trait that was masked in the F1 generation (p. 278)
Principle of Dominance
In a hybrid organism, the organism that physically shows (p. 279)
Phenotype
Observable characteristic or outward expression of an allele pair (p. 279)
Genotype
Organisms’ allele pairs (p. 279)
Homozygous
Organism of two of the same alleles for a particular trait (p. 279)
Heterozygous
An organism with two different alleles
Law of independent assortment
Random distribution of alleles occurs during gamete formation (p. 280)
Law of segregation
Two alleles for each trait separate during meiosis (p. 279)
