The following pedigree shows the pattern of inheritance of red-green color blindness in a family. Females are shown as circles and males as squares; the squares or circles of individuals affected by the trait are filled in black. What is the chance that a son of the third-generation female indicated by the arrow will be color blind if the father is not color blind? If he is color blind?
Sickle cell anemia is a human genetic disorder caused by an autosomal recessive allele. A couple plan to marry and want to know the probability that they will have an affected child. With your knowledge of Mendelian inheritance, what can you tell them if (1) each has one affected parent and a parent with no family history of SCA or (2) the man is affected by the disorder but the woman has no family history of SCA?
Two average-sized parents have three children. The first child is very short, the second very tall, and the third is average in height. Explain the inheritance pattern for height in this family. In particular, how is it possible for the parents to have both very short and very tall children?
Over the years, Mendel experimented with more than 30,000 pea plants. Why did Mendel collect data on so many plants? Why didn’t he study just one cross? Hint: Read “What Are the Odds?” on page 124 before answering.
Mendel’s observation that two different traits could be inherited independently of each other can be explained by understanding that: During meiosis, the process of chromosome assortment into daughter cells is random Alleles of the genes reside on homologous chromosomes All of the listed choices are correct During meiosis, maternal and paternal members of homologous chromosomes are distributed separately into daughter cells
In pea plants, smooth peas is dominant to wrinkled peas. When Mendel crossed true breeding smooth peas with true breeding wrinkled peas, what is the genotype of the offspring and what percentage?
Gray seed color in peas is dominant to white. Assume that Mendel conducted a series of experiments where plants with gray seeds were crossed with each other and the following progeny were produced: 320 gray and 80 white. (a) What is the most probable genotype of each parent? (b) Based on your answer in (a) above, what genotypic and phenotypic ratios are expected in the progeny?
Mendel performs a cross using a true-breeding pea plant with round, yellow seeds and a true-breeding pea plant with green, wrinkled seeds. What is the probability that offspring will have green, round seeds? Calculate the probability for the F1 and F2 generations.
Two healthy parents have a child who is later diagnosed with cystic fibrosis. What is the genetic term for this kind of disease? Using Mendel’s pattern, pick a letter for this gene and give the genotypes of the parents and the child. What are the odds that their next child will also have cystic fibrosis?
Name and describe Mendel’s two laws.
Hemophilia is a sex-linked recessive trait. A male hemophiliac and phenotypically normal female have a son with hemophilia. They would like to have one more child. What is the probability of having a child without hemophilia? Explain using a Punnett square. Is it possible for a girl to be born with hemophilia? Explain.
Using the given pedigree chart, suppose individuals III-1 and III-2 are expecting their sixth child. What is the chance (percent) that the sixth child will have the sickle cell trait?
