Gene Flashcards
the particles that Mendel stated as traits were
chromosomes & DNA
the trait that seems to mask the recessive
dominant trait
the trait that becomes masked and fades into the background first
recessive trait
how many alleles from each parent
1 from each
Genes:
sections of instructions in a chromosome that code for a specific trait
Trait:
An aspect of your appearance (hair color, eye color)
Allele:
All the options available for a trait (blonde, black, red)
Genotype:
letters to represent specific alleles from a trait
Phenotype:
This is the physical appearance of genotype
How many representations does genotype have
2
Hetero:
Different
Homo:
Same
Dihybrid Cross:
Cross to find all possible combinations of traits for each parent
If gene affects the physical appearance of organism, it is
expressed
if gene does not affect physical appearnce,
unexpressed
Codominant:
Both genes are expressed
Incomplete dominance:
combination of the genes - 3rd gene
