- If a couple has six boys, what is the probability that a seventh child will be a girl?arrow_forwardTwo people heterozygous for Tay-Sachs (recessive disease) have two children who are both normal. What are the chances of their third child having Tay-Sachs? What are the chances of their fourth child having Tay-Sachs?arrow_forwardA student who has just learned about quantitative genetics says, “Heritability estimates are worthless! They don’t tell you anything about the genes that affect a characteristic. They don’t provide any information about the types of offspring to expect from a cross. Heritability estimates measured in one population can’t be used for other populations, so they don’t even give you any general information about how much of a characteristic is genetically determined. Heritabilities don’t do anything but make undergraduate students sweat during tests.” How would you respond to this statement? Is the student correct? What good are heritabilities, and why do geneticists bother to calculate them?arrow_forward
- A couple is going to have a baby. They are concerned about sickle cell anemia, which results from having the homozygous recessive combination of the sickle cell gene ("s"), which produces abnormal hemoglobin. Having at least one normal version of the gene ("S") results in normal hemoglobin. The woman is heterozygous, and so is the man. What alleles does mom have? What alleles does dad have?arrow_forwardWhat do you think is going on with these two families? The hospital would have simple things like Diana’s blood type on file as below.

If the line ends with either a circle or a square, the couple had only one child. However, if the line is connected to another horizontal line, then several children were produced, each indicated by a short vertical line connected to the horizontal line. The first child born appears to the left and the last bor to the right. a. How many children did the first couple (couple in row D) have? b.
