Mendelian Genetics
Who is Gregor Mendel?
Two dominant phenotypes
What is codominance?
Two traits, neither of which is dominant
What is incomplete dominance?
Capital letters that always express the trait when present
What is a dominant trait?
The organisms that Mendel studied
What are pea plants?
Offspring of this cross are 100% RW (red & white)
What are RR x WW?
All possible phenotypes when crossing a red flower with a white flower
What is red, white, and pink?
Two of the same alleles
What is homozygous?
The letters that represent genes
What are alleles?
What is RW x RW?
What is RR x WW?
A gene depicted by one capital letter and one lower case letter
What is heterozygous?
100% of the offspring of cross are heterozygous
What are TT x tt?
Offspring of this cross are 50% WW and 50% RW
What is RW x WW
The offspring of these parents both have curly hair
What are CC x SS?
The physical trait seen on an organism
What is phenotype?
Offspring of this cross are 25% homozygous dominant
What is Rr x Rr?
Offspring of this cross are 100% RR
What is RR x RR?
The offspring of these parents have straight, curly and wavy hair
What is CS x CS?
A trait with the following alleles: RR
What is homozygous dominant?
