-study of character inheritance
-codes for specific character traits
-position on a homolog
-gene form / occupies a loci
What are the allele types?
Dominant and Recessive
What does allele interaction dictate?
-alleles are identical
-both alleles dominant
-both alleles recessive
-different allele combinations
-different observed expressions
What are the different dominance levels between alleles?
-Complete Dominance: dominant allele completely covers recessive allele
-Incomplete dominance: Dominant allele does not completely mask recessive allele.
-Co-Dominance: alleles equally dominate and are both fully expressed.
Two flowers are crossed
Dominant Red RR plant & Recessive white rr plant.
What will the phenotype and genotype be considering dominance levels?
Complete : Rr red
Incomplete Rr pink
What is a monohybrid cross?
What is a di-hybrid cross?
1 character cross
2 character cross
What is a Punnett Square used for?
predicting genotypic and phenotypic offspring ratios.
-first generation offspring
-second generation offspring
What is the gamete number formula for crosses?
N = number of characters
