5.1 Mendelian Genetics Quiz

truebreeding

when self pollinated or crossed with similar true-breed the offspring with have the same trait

Eg of truebreedinf

purple flower pea plant with true breeding purple flower yields all purple flower. (hybrid)

monohybrid

the offspring of two different true-breeding organism that differ in only one characteristic

monohybrid cross

cross that studies inheritance of one trait

trait

version of a characteristic that is inherited

genotype

genetic makeup of individual

phenotype

outward appearance with respect to specific characteristic

allele

version of a gene

dominant allele

always expressed

recessive allele

only expressed if homozygous

test cross

determines genotype of individual expressing dominant trait

P generation

Parent organisms that are mated

F1 generation

offspring of P generation

F2 generation

breeded offspring of the hybrid F1 generation.
