Answer 3

dominant and recessive

Question 4

incomplete dominance

Answer 4

blending of dominant and recessive alleles for the heterozygous (black x white = gray)

Question 5

express (black x white = Black and white spots)

Question 6

linked genes

Answer 6

2 genes must be on the same chromosome (also known as recombinant frequency)

Question 13

Interphase

Answer 13

where a cell is copied and then preped for cell divison

Question 13

metaphase

Answer 13

this step is before interphase and lines up all of the cells for it to be properly divided
