Mendelian Genetics Group Lab Report(20 points)did not have access to F1and F2seedlings (intl. lab kit)A. Predictions1. (1 pt) The P1plant was a purple stem, normal height plant (PPSS) and the P2plant was a non-purplestem, dwarf plant (ppss), and both plants were homozygous for these two traits.Draw the cross of the Pand P2parental plants. Based on this cross, what is the predicted phenotype of all of the F1plants?1(Phenotypic ratio, Biology Online)2. (1 pt) Two F1plants were crossed.Taking only stem color into consideration, what phenotypic ratio doyou expect for the F2generation seedlings and why?
3. (1 pt) Taking only stem height into consideration, what phenotypic ratio do you expect for the F2generation seedlings and why?
recessive allele can only have one genotype (ss - homozygous recessive), and only one phenotype,appearing dwarf in height. When the two hybrid normal height plants from the F1generation are crossed,there is one homozygous dominant plant, two heterozygous plants, and one homozygous recessive plantin the F2generation. Because the homozygous dominant and heterozygous plants both appear normalheight, there will be three normal height phenotypes. The homozygous recessive plant appears dwarf inheight, so there is dwarf phenotype. This results in a 3:1 phenotypic ratio.4. (1 pt) Taking both stem color and height into consideration, what phenotypic ratio do you expect,considering both traits together, for the F2generation seedlings.Explain (show your math or a PunnettSquare).
