Heredity
inherited features that vary from individual to individual
What is character?
alleles on chromosomes
What is genotype?
Segment of DNA that codes for a protein
What is a gene?
Total used to predict different mating outcomes
What is a Punnett Square?
Two white-flowered pea plants (pp x pp) are crossed. What percent of offspring have white flowers?
100%
different characters variations
What is traits?
physical expression of a trait
what is phenotype?
When a plant's offspring shows a blended trait
What is incomplete dominance?
typically produced by crossing two plants in same genus (closely related)
what is a hybrid?
A homozygous purple plant (PP) is crossed with a white plant (pp). What percent of offspring are purple?
100%
alternate forms of a gene
what is alleles?
expresses if it is the ONLY allele present
What is recessive alleles?
When a plant shows both traits from its parents at the same time
What is codominance?
regulates transgenic plants
What is USDA, FDA, EPA?
A heterozygous purple plant (Pp) is crossed with a white plant (pp). What percent of offspring are purple?
50%
the human driven process of breeding organisms to obtain desirable traits over generations
What is selective breeding?
expressed if present
What is dominant alleles?
two identical alleles for a gene
What is homozygous
the father of genetics
Who is Gregor Mendel?
Two heterozygous purple plants (Pp x Pp) are crossed. What percent of offspring are purple?
75%
contains recombinant DNA (rDNA)
What is transgenic organisms (GMOs)?
a "blending" or intermediate between the homozygous parents
What is incomplete dominance?
two different alleles for a gene
What is heterozygous?
How you "amplify" genes when creating transgenic organisms
What is PCR copies DNA?
Two purple plants are crossed. One is PP and one is Pp. What percent of the offspring have white flowers?
0%
