You do a cross between a blue and a white flower. You expected to see progeny produced in the typical mendelian ratio of 3:1. You observe 65 blue flowers and 35 white flowers. After performing a Chi Square calculation do you accept or reject the hypothesis that the color pigment for this particle flower is controlled by one gene?

1) For the Drosophila red/white cross, you crossed red females and white males (w'w, wy). a) Draw the Punnett Square for this cross (F1). What is the ratio of red females:red males? b) Suppose in the F1 generation, you observed 70 red females and 30 red males.

7. A red snapdragon flower is crossed with a white snapdragon flower. All of the offspring are pink snapdragon flowers. You study the pink snapdragon flowers and discover that these flowers produce red pigment but at low levels, thus causing the pink color. What type of genetic inheritance is this? What is the genotype of the red snapdragon flower? What is the genotype of the white snapdragon flower? What is the genotype of the pink snapdragon flower? You cross a...

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...

In a species of plant, two genes control flower color. The red allele (R) is dominant to the white allele (r); the color producing allele (C) is dominant to the non color producing allele (c). You suspect that either an rr homozygote or a cc homozygote will produce white flowers. In other words, rr is epistatic to C, and cc is epistatic to R. to test your hypothesis, you allowed heterozygous plants (RrCc) to self fertilize and count the offspring....
