Chapter 10.1-10.2 Vocab Flashcards
The study of heredity
Genetics
A cross; sperm from the pollen of one flower fertilizes the egg in the flower of a different plant
Cross fertilization
The offspring of two different true breeding varieties
Hybrids
A pairing in which the parent plants differ in only one (mono) character
Monohybrid cross
Alternative forms of genes
Alleles
Individual in which the two alleles are the same
Homozygous
Individual in which the two alleles are different
Heterozygous
When only one of the two different alleles in a heterozygous individual appears to affect the trait
Dominant
In allele that does not appear to affect the trait
Recessive
Type of diagram that shows all possible outcomes of a genetic cross
Punnets square
Observable traits
Phenotype
Genetic make up, or combination of alleles
Genotype
Breeds in individual of unknown genotype, but dominant phenotype with a homozygous recessive individual
Testcross
Crossing organisms differing in 2 characters
Dihybrid cross
A variation of a particular character
Trait
