Chapter 20, Problem 35P
The following is a partial pedigree of the British royal family. The family contains several inbred individuals and a number of inbreeding pathways. Carefully evaluate the pedigree, and identify the pathways and common ancestors that produce inbred individuals A (Alice in generation IV), B (George VI in generation VI), and C (Charles in generation VIII).

The pedigree shown below depicts crosses performed as part of an antelope captive-breeding program. Use the pedigree information to calculate the coefficient of inbreeding (F) for the mating of IV-12 and III-9 that produces the animal identified as V-13.
What could be the genotypic and phenotypic ratios for a typical mendelian trait showed in the picture?
A family pedigree is shown here.
A. What is the inbreeding coefficient for individual IV-3?
B. Based on the data shown in this pedigree, is individual IV-4 inbred?

- Make a pedigree analysis on a five generation family using both maternal and paternal side. (great great grandparents as generation 1) All have a light brown skin color and straight hair. Use attached photo as a reference. (All names with highlighted yellow color are female. The rest are male. Name with red is deceased person. Name with green color are their spouse. Name with underline is the 5th gen (kids) )arrow_forwardA dark-red strain and a white strain of wheat are crossed andproduce an intermediate, medium-red F1. When the F1 plants areinterbred, an F2 generation is produced in a ratio of 1 dark-red:4 medium-dark-red: 6 medium-red: 4 light-red: 1 white. Furthercrosses reveal that the dark-red and white F2 plants are truebreeding. How many additive alleles are needed to produce each possiblephenotype?arrow_forwardComplete a Punnett square for a genetic cross of two truebreeding Portuguese water dogs—one with a black, wavy coat (homozygous dominant, BBWW) and one with a brown, curly coat (homozygous recessive, bbww). What is the phenotype ratio of their offspring (F1)? Now fill out another Punnett square, crossing two of the offspring. What is the phenotype ratio of the F2 generation?arrow_forward

In 2016, assume in the City of Markham there are 1000 people out of 300000 people who have sickle cell anemia. Assume global warming continues for the next 50 years and in the year 2066 there are 20000 people out of 500000 in Markham who have sickle cell anemia. a)What are the allele frequencies in 2016? What are the allele frequencies in 2066? Is microevolution evident? b)Due to global warming, assume the numbers of malaria carrying mosquitoes in Markham dramatically increased between 2016 and 2066.

- Draw out a pedigree with 3+ generations that accurately mimics the inheritance patterns for one of the following: Huntington’s disease, sickle cell anemia, or genetic hemophilia. In your pedigree, be sure to properly denote carriers as well as people with the condition. Additionally, include the following, using proper pedigree conventions: a stillbirth and an incidence of inbreeding.arrow_forwardBelow is a pedigree of a family in which all the people in generation II are dead (indicated with a slash) because of political unrest in their country. Which children in generation III could be traced to the grandmother in this pedigree by using only mitochondrial DNA sequences? a. A and D b. A, B, and C c. A, B, C, D, and E d. B, C, and Earrow_forwardA genetic engineer is going to cross two watermelon plants to produce seeds for a spring planting. He is breeding for size, and wants to have as many watermelons with the phenotype for long shape as possible. In watermelons, the allele for short shape (R) is dominant to the allele for long shape (r). Would crossing a watermelon homozygous recessive for the trait with a watermelon heterozygous for the trait give the most long watermelons possible? Explain your answer using Punnett Squares.arrow_forward
- In Mendel’s 1866 publication as shown in Figure 1-4, he reports 705 purple-flowered (violet) offspring and 224 white-flowered offspring. The ratio he obtained is 3.15:1 for purple: white. How do you think he explained the fact that the ratio is not exactly 3:1?arrow_forwardTwo individuals, labeled A and B as shown in the following figure, what is the probability of individual A and B shares a same allele, as a result of their descent from a common great grandparent?arrow_forwardIn oats, the color of the chaff is determined by a two-gene interaction. When a true-breeding black chaff plant was crossed to a truebreeding white chaff plant, the F1 generation was composed of allblack chaff plants. When the F1 offspring were crossed to eachother, the ratio produced was 12 black to 3 gray to 1 white. First,construct a Punnett square that accounts for this pattern of inheritance. Which genotypes produce the gray chaff phenotype? Second,at the level of protein function, how would you explain this type ofinheritance?arrow_forward
