100
This gene always shows is self over a recessive gene
Dominant Gene
100

46
100
Organized display of all the chromosomes an organism has arranged from biggest to smallest
karyotype
100
a capital letter represents ______ type of trait
Dominant
200
The passing of traits from parent to offspring is called.
Heredity
200
genotype that has two of the same alleles
homozygous
200
type of non-mendelian genetics where both alleles show.
ex. red and white flowers
co-dominance
200
Term used for DNA replication that describes the process of separating and using the old strands as templates for the new nucleotides to pair with, so that both copies are identical. Half old and half new
Semi-Conservative
200
type of non-mendelian genetics that have an in-between phenotype.
ex. Red + white flowers = pink offspring
