Vocab Quiz Flashcards
Genotype
The genetic make up or combination of alleles of the offspring
Zygotes
Single diploid (2n) cell that is formed when 2 gametes fuse during fertilization
Phenotype
The physical appearance of the alleles of the offspring
Gregor Mendel
Father of heredity
Codominance
Occurs when 2 alleles are expressed equally in the offspring
Incomplete dominance
Occurs when 2 alleles produce three phenotypes
Heredity
Branch of genetics dealing with the passing on of traits from parents to offspring.
Monohybrid
experiment where the 2 parents differ by only 1 trait
Allele
Genetic factor that controls the expression of a gene.
Heterozygous
The alleles on the chromosomes for a certain trait are different and the dominant allele is shown.
Mendelian Inheritance
Inheriting traits that are controlled by one pair of alleles.
Homozygous
Both alleles on the chromosomes for a certain trait are the same.
Gametes
Sex cells (sperm & egg)
Inbreeding
Fertilization of gametes that are from the same parent or closely related parents.
Outbreeding
Fertilization of gametes by unrelated parents
F1 Generation (outbreeding)
first set of offspring that come from 2 non related parents
F2 Generation
Bred members of f1 together (inbreeding)
Dominant trait
The observable trait in F1 generation
Recessive Trait
The trait that’s hidden in the f1 generation, but reappears in the F2.
Diploid
Possessing all of the total number of chromosomes.
Haploid
Possessing 1/2 of the total number of chromosomes.
