Answer:
Data given:
In a population of fruit flies - 37.5% possess a particular trait, T.
It is given that 25% of the females possess the trait.
The population is composed of equal numbers of males and females.
Probability that a fruit fly selected at random from the population, and it possesses the trait, is a female = ?
Now, using the above information, we can find the required probability as -
1. The population is composed of equal numbers of males and females.
It is given that 25% of the females possess the trait.
Since it is given that the randomly selected fruit fly is found to possess the the trait, T, therefore the probability of the selected fruit fly to be a female can be computed as -
Thus, the probability that a fruit fly selected at random from the population, and it possesses the trait, is a female is approximately 0.33 .
In a population of fruit flies, 37.5% possess a particular trait, T. Suppose 25% of the...
You make cross between a male fruit fly with wrinkled wings and a female fly with vestigial wings. All of the F1 flies are have wrinkled wings. A cross between an F1 female fly and an F1 male fly yields the following offspring: 45 wrinkled-wing males 51 wrinkled-wing females 18 vestigial-wing males 14 vestigial-wing females What do you hypothesize as the mode of inheritance for this trait?
A genetics experiment involves a population of fruit flies consisting of 1 male named Andre and 3 females named Barbara, Carla, and Diana. Assume that two fruit flies are randomly selected with replacement. a. After listing the possible samples and finding the proportion of males in each sample, use a table to describe the sampling distribution of the proportion of males.
2. Some biology students were checking the eye color for a large number of fruit flies. For the individual fly, suppose that the probability of white eyes is 25 and the probability of red eyes is .75, and that we may treat these flies as independent Bernoulli trials. Suppose that the biology students check the eyes of fruit flies until the third white-eyed fruit fly is observed. (a) What is the probability of observing third white-eyed fruit fly on the...
A genetics experiment involves a population of fruit flies consisting of 3 males named Alex, Bob, and Carlos and 1 female named Dana. Assume that two fruit flies are randomly selected with replacement. a. After listing the possible samples and finding the proportion of females in each sample, use a table to describe the sampling distribution of the proportion of females. Proportion of females Probability 0.5 1 (Type integers or fractions.) Use the accompanying data set on the pulse rates...
A certain population contains equal numbers of males and females. 40% of the population has long hair. 35% of the population is female with long hair. If an individual is randomly selected from this population, the probability that the individual is female or has long hair (or both) is

Suppose that 30% of mosquitoes possess a certain gene. A researcher wishes to obtain four mosquitoes that possess this gene. Find the probability that the researcher will obtain the fifth fly after sampling 15 flies from the general mosquito population?

Suppose that, in a certain population, heights of males are normally distributed with mean M1 = 178cm and standard deviation 01 = 4cm while heights of females are normally dis- tributed with M2 = 170cm and 01 = 3cm. Now suppose that a random sample of 25 males and 25 females are selected from the population. a) What is the probability that the average height of the males is greater than 180cm? b)...
Several crosses were made between female fruit flies with yellow bodies and short bristles and male flies with tan bodies and long bristles. The flies were from a mixed population, so they were not necessarily true breeding. The results are shown below. Cross 1: Females all tan with short bristles; males all yellow with short bristles Cross 2: Females half tan with short bristles, half tan with long bristles; Males half yellow with short bristles; half yellow with long bristles....

Analyze the following fruit fly cross. In this cross there are two autosomal traits that are influenced by two distinct genes and the F2 generation came from crossing an F1 male with an F1 female. P: true breeding grey eyed; brown bodied males x true breeding red eyed; black bodied females F1: all offspring are red eyed; brown bodied F2: ? When the Fy flies are allowed to self cross, what percentage of F2...
