Chapter 10 Flashcards
Principle of independent assortment
In and f2 cross a particular allele for one character can be paired up with either allele of another character
Polygenic inheritance
When a trait is affected by two or more genes
Intermediate inheritance
In which heterozygotes have a phenotype intermediate between the phenotype a of the two heterozygotes
Co-dominance
In which heterozygote expresses both traits AB blood- ia ib
Test cross
Breed and unknown dominant with a homozygous recessive
Allele
Alternative form of a gene
Hybrid
Offspring of two different try breeding parent
True bred
Parent pure bred parent “p” generation
Trait
Variation of a particular character
Cross fertilization
Sperm of one flower fertilizes the eggs of another
Blending hypothesis
Says that the traits of two parents blend in the offspring
*discarded
Particulate hypothesis of inheritance
Parents pass on to their offspring district factors(genes) that were responsible for inherited traits mended stressed that these heritable factors retain their identity generation after generation
