In the garden pea, yellow cotyledon color (Y) is dominant to
green (y), and inflated pod shape (P) dominant to constricted (p).
A yellow cotyledon/inflated pea plant (YYPP) was crossed with a
green cotyledon/constricted (yypp) pea plant. The resulting F1
hybrid plant displayed a yellow cotyledon and inflated phenotype.
Selfing the F1 plants was performed and the F2 numbers are shown

In a flowering plant, red flowers are dominant over white flowers, and short plants are dominant over tall plants. A short plant with red flowers was self-fertilized and the phenotypes for the resulting progeny recorded (see below). Based on the observed numbers, you propose the hypothesis that this dihybrid cross follows a 9:3:3:1 phenotypic ratio, whereby Mendel's laws apply. Based on this hypothesis, you calculated the expected number of progeny for each phenotype (see below). Phenotype Observed Number of Plants...
