You can assume as a background assumption that height in pea plants is completely hereditary. You can also assume that shortness is dominant. The F1 generation is the result of a monohybrid cross of two pure breeding parents. Does the data for the F1 generation disagree or not with a prediction from a population observation hypothesis based on Mendel's theory of inheritance?

3/22/24, 11:14 PM E2 Practice 9 Mendel Applied: PHIL 125 003 2023W2 Introduction to Scientific Reasoning Some the experiments Mendel did with pea plants were dihybrid crosses. For example, he crossed Parent1 = purebreeding green pea pod color, purebreeding wrinkled pea shape with Parent2 = purebreeding yellow pea pod color, purebreeding round or smooth pea shape In the F1 generation all the resulting pea plants had round or smooth and yellow peas or seeds. If the F1 generation members now are crossed with one another, according to Mendel's theory what is the probability that a member of the F2 generation will have wrinkled peas or seeds? The probability is 1/16 The probability is 2/16 The probability is 3/16 The probability is 4/16 The probability is 5/16 The probability is 6/16 The probability is 7/16 The probability is 8/16 The probability is 9/16 The probability is 10/16 The probability is 11/16 The probability is 12/16 The probability is 13/16 The probability is 14/16 The probability is 15/16 The probability is 16/16 Question 6 1/1 pts )< -) 0 @ A 3 4 Nn” Some the experiments Mendel did with pea plants were dinybrid crosses.

The variant of the factor for having a widow's peak is dominant (W) and the variant for having a continuous hairline is recessive (w). Suppose a genetics counsellor knows that one of the parents is WW for having a widow's peak and the other is Ww for this characteristic. Then what can the genetics counsellor tell these parents about their children? They each have a 100% chance of having a widow's peak (and a 0% chance of having a continuous hairline). They each have a 75% chance of having a widow's peak (and a 25% chance of having a continuous hairline). They each have a 50% chance of having a widow's peak (and a 50% chance of having a continuous hairline). They each have a 25% chance of having a widow's peak (and a 75% chance of having a continuous hairline). They each have a 0% chance of having a widow's peak (and a 100% chance of having a continuous hairline). PartialQuestion 8 0.67 /1 pts Many observable inherited characteristics in human beings obey Mendel's laws or rules. This is important for genetics counsellors to know. An example is being able to roll your tongue. The variant of the factor for being able to do this is dominant (R) and the variant for not being able to do this is recessive (r). Suppose a genetics counsellor can see that the one child in a family cannot roll his or her tongue. (There is only one child.) Then what can the genetics counsellor tell about the parents? The answers below give the possibilities. More than one could be right. In this question you have to Iindicate all and only the correct answers. Both parents might be RR. Both parents might be Rr. Both parents might be rr. One parent might be RR and the other Rr One parent might be RR and the other rr One parent might be Rr and the other rr Question 9 1/1 pts https://canvas.ubc.ca/courses/132235/quizzes/708108 6/9

This is important for genetics counsellors to know. An example is being diabetic. This is a disorder of the pancreas. Insulin is either not produced or is not effective. The result is that blood sugar levels aren't properly controlled. Diabetes is a recessive disorder (d). Suppose a genetics counsellor can see that some children in a family have diabetes and some don't. Then what can the genetics counsellor tell about the parents? The answers below give the possibilities. More than one could be right. In this question you have to indicate all and only the correct answers. Both parents are DD. Both parents are Dd. Both parents are dd. One parent is DD and the other Dd One parent is DD and the other dd One parent is Dd and the other dd Question 10 1/1 pts <!

The factor that codes for this molecule has three variants or versions: A, B, and o. The o version is recessive and the A and B versions of the factor are equally dominant. The resulting blood types are in the table. The genetic factor for blood types only partly follows Mendel's rules or laws. Mendel's rules say that there can only be two versions of a factor. Mendel's rules also say that one and only one is dominant. But in all other ways, these factors follow Mendel's laws. Suppose a genetics counsellor knows that one of the parents has blood type B (with a factor B and a factor 0) and the other blood type AB. Then what can the genetics counsellor tell these parents about their children? They each have a 100% chance of being blood type AB (and a 0% chance of not). They each have a 75% chance of being blood type AB (and a 25% chance of not). They each have a 50% chance of being blood type AB (and a 50% chance of not). They each have a 25% chance of being blood type AB (and a 75% chance of not). They each have a 0% chance of being blood type AB (and a 100% chance of not).

3/22/24, 11:14 PM E2 Practice 9 Mendel Applied: PHIL 125 003 2023W2 Introduction to Scientific Reasoning Blood typing is important for blood transfusions. A person given the wrong blood type in a transfusion can die. The table also shows what blood type a person can safely receive or donate. A person is called a universal recipient if they can safely receive blood of any type in a transfusion and a universal donor if they can donate blood to anyone. Suppose a genetics counsellor knows that both of the parents are blood type AB. Then what can the genetics counsellor tell these parents about their children? They each have a 100% chance of being a universal recipient (and a 0% chance of not). They each have a 75% chance of being a universal recipient (and a 25% chance of not). They each have a 50% chance of being a universal recipient (and a 50% chance of not). They each have a 25% chance of being a universal recipient (and a 75% chance of not). They each have a 0% chance of being a universal recipient (and a 100% chance of not). Quiz Score: 9.67 out of 11 https://canvas.ubc.ca/courses/132235/quizzes/708108 9/9
