1) The observed numbers for dominant and recessive types in an F2 generation are 154 and 46. You would assume the expected numbers to be in a ---------- to 1 ratio. would the answer for question 1 be a 3 to 1 ratio i'm really confused. 2) Looking at the observed numbers in question 1 what would your expected number of dominant types be? I don't know please help. 3) Using the same observed numbers in question 1 what would...

Punnett Square for Question #4 is a the top
Punnett Square Genotypic ratio: Phenotypic ratio: 5. Purple flowers (P) are completely dominant over white flowers (p). If a pea plant is heterozygous for purple flowers, can any of this plant's offspring have all purple flowers? Think about the different genotypes with which you can cross the hetero- zygous parent: homozygous dominant, heterozygous, and homozygous recessive. Use three Punnett squares to show your work for each possible phenotype. Heterozygous purple pea...
