Crossing pea plants and observing traits of the offspring
How did mendel study inheritance?
What is simple dominance?
The random change in the ratio of alleles in a population?
What is genetic drift?
determines an organisms phenotype
What is genotype?
The phenotype is expressed in the hybrid offspring
What is one principle of heredity?
a cross between red and white snapdragons resulting in a pink flower
What is incomplete dominance?
The process where beneficial adaptations that increase survival are passed on to offspring
What is natural selection?
A capital and lowercase of the same letters together
What depicts a hybrid genotype?
an organisms genotype is the combo of alleles it inherited from parents
What is a second principle of heretidy?
What results from codominance with IA and IB?
Both decrease the amount of genetic information in a population
What are genetic drift and natural selection?
a polygenic trait controlled by 424 genes
What is height?
An organisms phenotype consists of traits coded from the genotype
What is the third principle of heredity?
When more than one gene is responsible for a phenotype
What is polygenic inheritance?
in the desert a fox with big ears is likely to increase or decrease
What is increase?
simple dominance
What occurs when the hybrid offspring only shows the dominant trait?
this results in hybrid peas with all green pods
What is a cross of purebred dominant and purebred recessive parents?
a gene has more than two possible alleles
What are multiple alleles?
the result of a cross with an incomplete dominant trait for black or white wool
What would cause grey wool?
