In Europe, 53% of the flowers of the Rewardless Orchid, Dactylorhiza sambucina, are yellow, whereas the remaining flowers are purple.

In Europe, 53% of the flowers of the Rewardless Orchid, Dactylorhiza sambucina, are yellow, whereas the remaining flowers are purple. For this problem, only use the normal approximation where it is appropriate. Use the binomial distribution where the normal approximation is inappropriate.

If we took a random sample of a single individual from this population, what is the probability, reported as a percent, that it would be purple?

Determine the probability, reported as a decimal rounded to two decimal places, that if we took a random sample of 6 flowers, at least 3 would be yellow.

If we took a random sample of 260 individuals, what is the probability, reported as a decimal rounded to two decimal places, that 150 or fewer of the orchids are yellow?

An urn contains 5000 balls, of which 100 are yellow and the remaining are purple. We draw 20 balls from the urn and denote the number of yellow balls drawn by X. (a) What kind of random variable is X if the draws are performed without replacement? Write down the probability distribution function f(x) of X and compute P(X = 5). (Give an exact expression for the probability that is asked but do not evaluate!) (b) What kind of random...

In tomatoes, yellow flowers (Wf) are dominant over white flowers (wf), and yellow fruit (r) are recessive to red fruit (R). A cross was made between true-breeding plants with yellow flowers and yellow fruit, and plants with white flowers and red fruit. The F1 generation plants were then crossed to plants with white flowers and yellow fruit. The following results were obtained: 75 white flowers, red fruit 205 white flowers, yellow fruit 216 yellow flowers, red fruit 37 yellow flowers,...

A wild legume with white flowers and long pods is crossed to one with purple flowers and short pods. The F1 offspring are allowed to self-fertilize, and the F2 generation has 301 long purple, 99 short purple, 612 long pink, 195 short pink, 295 long white and 98 short white plants. How are these traits being inherited? Inheritance of these traits can best be explained by one gene with 3 different alleles. Inheritance of these traits can best be explained...

A pea plant requires an enzyme to produce flowers that are purple. If this enzyme is NOT functional, the flowers will be all white. Based on this information, which of the statements are true? A. All of the answers provided are true. B. The functional form of the protein is encoded by a recessive allele. C. The non-functional form of the protein is encoded by a recessive allele.

Populations evolve for many reasons. Suppose there is a population of plants that have either purple flowers or white flowers

Populations evolve for many reasons. Suppose there is a population of plants that have either purple flowers or white flowers, and the allele for purple flowers is dominant. This means that plants with two purple alleles have purple flowers. Plants with one purple allele and one white allele also have purple flowers. Only plants with two white alleles have white flowers. For each event or condition described below, answer the following questions. Which mechanism of evolution is at work? How...

For these binomial settings, give the parameters n and p. a) Orchid flowers can be “left-handed” or “right-handed” depending on the position of certain structures. 25% of flowers are left-handed.

A cross was made between a plant that has blue flowers and purple seeds to a plant with white flowers and green seeds. This is a parental cross and the parents are homozygous for both characters (color of the flower and color of the seeds). The resulting offspring (the F1 generation) is allowed to self-fertilize. Complete a Punnett square representing the F2 generation that results from the above self-fertilization. The traits blue flowers (B) and purple seeds (P) are dominant...
