In sweet pea plant, an allele for purple flowers (P) is dominant when paired with a recessive allele for red flowers (p). An allele for long pollen grains (L) is dominant when paired with a recessive allele for round pollen grain (l). Bateson and Punnett crossed a plant having purple flowers/long pollen grains with one having white/flowers/round pollen grains. All F1 offspring had purple flowers and long pollen grains. Among the F2 generation, the researchers observed the following phenotypes: 296 purple flowers/long pollen grains 19 purple flowers/round pollen grains 27 red flowers/long pollen grains 85 red flowers/round pollen grains What is the best explanation for these results?

Use the following information to answer the next question. A monohybrid cross of two pure forms of red flowers and white flowers in Mirabilis jalapa plant with genotypes R¡R1 and R2R2 produced all pink flowers. The F2 generation produced a phenotypic and genotypic ratio of 1: 2: 1. Which genetic mechanism can account for these results? O dihybrid cross O incomplete dominance O co-dominance O multiple alleles

Do a chi square tablet for the question. I left a reference down below. Question: 3. In dihybrid cross where both parents were heterozygous for both traits, the following data was obtained: 890 dominant for both traits, 97 recessive for both traits, 315 dominant for trait 1, but recessive for trait 2, and 298 dominant for trait 2, but recessive for trait one. Perform a chi-square analysis to determine if this data agrees with the expected outcomes. State your null hypothesis as well as if the null is rejected or not.
