Problem: A homozygous tall, homozygous white flower plant crosses with a homozygous short, homozygous purple flower plant. We know that the purple and tall flowers are the dominant traits. Show your work.
What are the phenotypes of the offspring?
DRAW IT Pea plants heterozygousfor flower position and stem length(AaTt) are allowed to self-pollinate,and 400 of the resulting seeds areplanted. Draw a Punnett square forthis cross. How many offspring wouldbe predicted to have terminal flowers and be dwarf? (See Table 14.1.)

- The crab spider, Thomisus spectabilis, sits on flowers and preys upon visiting honeybees. Do honeybees distinguish between flowers that have crab spiders and flowers that do not? To test this, Heiling et al. (2003) gave 34 bees a choice between 2 flowers: one with, and one without a crab spider. In 24 of the 34 trials, the bees picked the flower that had the spider. In the other trials, the bees chose the spiderless flower. With these data, carry out the appropriate hypothesis test (one- or two-tailed), using the normal approximation to the binomial distribution to determine Z. For a one-tailed test, use the formula =(1-NORM.DIST(Z,0,1,TRUE) in Excel calculate P. For a two-tailed test, use the formula =2(1-NORM.DIST(Z,0,1,TRUE). State your answer for the value of P to three decimal places, and include the leading zero. Do all of the math in Excel DO NOT round the value of Z. Substitute the cell (e.g. B1) for Z in the formula for P.arrow_forwardA heterozygous plant with genotype Aa self-pollinates, and then its offspring also self-pollinate. Find the probability that the offspring of the offspring are tall for the following genetics systems. Half of heterozygous plants and one fourth of homozygous plants are tall (it depends on their position in the greenhouse).arrow_forward3. The inheritance of petal color in some plant species is alleged to be codominant. A group of pure (homozygous) white carnations were deliberately pollinated with pollen from pure red carnations. Fertilized seeds were collected, and after germination and growth of this F1 generation, they were allowed to freely pollinate one another. The color of the flower on each plant in the F2 generation was tallied. 239 red, 307 white, and 615 pink plants were recorded. Apply a ?2 analysis to determine the statistical validity of the assumed inheritance pattern. Show every step in your thought process along with all relevant calculations and written support. HINT: For this problem, you should DEFINITELY construct the two Punnett squares to reveal the phenotypes of the F1 and F2 generations. Please answer very soon will give rating surelyarrow_forward
- EXAMPLE PROBLEM A plant with orange, spotted flowers was grown in the greenhouse from a seed collected in the wild. The plant was self-pollinated and gave rise to the following progeny: 88 orange with spots, 34 yellow with spots, 32 orange with no spots, and 8 yellow with no spots. What can you conclude about the dominance relationships of the alleles responsible for the spotted and unspotted phenotypes? What can you conclude about the genotype of the original plant that had orange, spotted flowers?arrow_forwardA heterozygous plant with genotype Aa self-pollinates.
