name all of mr erickson kids
warren, greta, hagen, anika
The genetic expression of traits for an organism.
genotype
The cell spends most of its time in phase with its extra organelles, proteins, and chromosomes are ready for the four phases of mitosis and cytokinesis.
interphase
what is the difference between codominance and incomplete dominance?
co dominance both traits are expressed, incomplete traits are blended
the number of mutations in a Gene Pool
what is gene pool?
all the genes inside of a group of organisms
what is heterozygous? provide an example
having two different alleles for a gene, Aa, Bb, Cc
How many cells are produced during Telophase II.
4 gamete cells
50% Bb 50% bb
list three ways to kill abnormal cells.
cut, poison, burn
A family history that charts a heredity trait through generations.
pedigree
Genotypes of the same allele
homozygous
Which phase is the last phase of mitosis where chromosomes uncoil and reappear as chromatin?
telophase
what is the offspring of a poppy with incomplete dominace Cr x Cw and Cr x Cw
pink Cr x Cw, Red Cr x Cr and white Cw x Cw
What do people with down syndrome have?
Both alleles for a trait are expressed at the same time and are blending.
incomplete dominance
