The F1 flies described in question 1 were mated with brown-eyed flies from a true-breeding line. What phenotypes would you expect the offspring to have? (a) all with red eyes (b) all with brown eyes (c) half with red eyes and half with brown eyes (d) red-eyed females and brown-eyed males (e) brown-eyed females and red-eyed males
Imagine that you are performing a cross involving seed texture in garden pea plants. You cross true-breeding round and wrinkled parents to obtain F1 offspring. Which of the following experimental results in terms of numbers of plants are closest to what you expect in the F2 progeny? a. 8lOroundseeds b. 8lOwrinkledseeds c. 405:395 round seeds:wrinkled seeds d. 610:190 round seeds:wrinkled seeds
Wild type fruit flies have red eyes and normal wings. You crossed a male from a pure-breeding, purple-eyed, broken-winged line of fruit flies to a female from a pure-breeding, red-eyed, normal-winged line of fruit flies. All the F1 progeny were wild type. The reciprocal cross gave the same result. The F1 flies from the first cross were mated to produce an F2 population. If there were 528 flies in the F2 population how many would be purple-eyed and normal winged? 396 264 297 99 352
We have crossed true-breeding flies today. Wild type to mutant. Their phenotypes were wt and vg se. (Let’s not worry about males and females for now, just assume both genes are autosomal, which is normal in a Mendelian experiment). The results of a cross are phenotypes. I will be asking you for numbers or a ratio of phenotype numbers you expect to see in the offspring from this cross. To answer this, you’ll need to start with the genotypes of parents, then write their gametes, then write the offspring genotypes, then get the phenotypes based on them. Predict the results of this cross: In case both mutations are recessive; In case both mutations are dominant; In case vestigial wings are recessive and the sepia eyes are dominant.
The Dracula gene makes mice active at night and only consume blood instead of normal food. You cross a normal black mouse with a vampire mouse. The first generation are all black, but then you cross F1 mice together and collect all the litters. You find that the F2 generation has 138 black mice, and 62 vampire mice. Your boss tells you that her working theory is that this is a case of simple dominance and asks you to perform a chi squared test to determine whether her hypothesis is correct. If she is correct, she expected 150 black, and 50 vampire mice. What is the chi squared value? the value is 3.84 Now the question is She decides that as long as there is greater than a 50% chance her theory is correct, she will publish the results. Based on your calculations, should she publish this study? would it be(yes or no)

You have been working with a species of giant moths. You've found that Dark color (D) is dominant to Light color (d). You capture a moth in the wild (Moth X) bearing the dominant phenotype but want to don't know its genotype. Using 1 cross, how would you determine its genotype?

Shakira, after successfully cross-pollinating gerber daisies decides the same process will work with four o'clock flowers. She crosses a purple flowered plant with a white flowered plant and ends up with the following results in the offspring. Why did the four o'clock flower plant give three phenotypes instead 2? 7:26
Scenario A In goats, black fur is dominant to red fur. The gene for this trait can be described as Bb (if you forgot why this is so, go back and reread the background information at the beginning of this exercise). A homozygous black female goat (nanny) is crossed with a heterozygous male (billy). 5 What is the probability of the goats having a red kid, i.e., what is the proportion of red kids? Record your answer as a percentage What is the probability of the goats having a black kid? Record your answer as a percentage.
You were given 1000 fruit flies to start a new laboratory colony. Before starting to breed your fruit flies, you decided to determine their genetic make up. You counted approximately 360 fruit flies that have vestigial wings, a recessive trait. If you decide to remove all the fruit flies with vestigial wings and only breed the flies with normal wings, what is the approximate frequency of individuals with vestigial wings in the F1 generation? 0.09 0.16 0.25 O 0.36 O 0.14
Arginine yasotocin (AVT) is a hormone implicated in reproductive function in fish. In a study investigating the role of AVT on mating success, a 4th year student performed a series of crosses to assess the effects of different alleles of the AVT gene (WT and ayt-) on mating success. The following figure provides the results of 4 different crosses. 100 E 80- 60 40 – 20 – O wt X ơwt ?
