Inheritance patterns are often more complex than predicted by simple
Extensions of Mendelian genetics for a single gene:
Which genetic relationships listed h the first column of the two tables above are demonstrated by the inheritance pattern of the ABO blood group alleles? For each genetic relationship, explain why this inheritance pattern is or is not an example.

In addition to the allelic pair determining pattern baldness in man (B,b), consider early baldness to be due to another autosomal allele (E) on a different pair of chromosomes and also dominant in males but recessive in females. The phenotype for ee may be late or nonbaldness depending on sex and the genotype for B, b alleles. Two doubly heterozygous persons marry.
What is the phenotype of the male parent?
What is the phenotype of the female parent?
Give the phenotypic ratio expected among male children of couples such as this one. Show corresponding genotypes for each phenotype mentioned in your phenotypic ratio.

A woman with fair skin, blond hair, and blue eyes gives birth to fraternal twins; the father has dark brown skin, dark hair, and brown eyes. One twin has blond hair, brown eyes, and light skin, and the other has dark hair, brown eyes, and dark skin. What Mendelian law does this real-life case illustrate and explain what this means in terms of the inherited alleles for these genes?
Many genetic disorders exhibit locus heterogeneity. Define andgive two examples of locus heterogeneity. How does locus heterogeneityconfound a pedigree analysis?

- 3:48 1 Drive Multiple genes or polygenic inheritance: An additive effect of two or more genes on a single phenotypic character. 16. Skin color appears to be controlled by several genes. This creates a continuum of variation) also seen in height, hair color, etc.) If this polygenic explanation of the inheritance of human skin pigmentation is correct, how do the skin colors of the following four individuals compare? Which of the couples could have children with the widest range of skin colors? Why? Couple 1: aaBbCC and aaBbCC Couple 2: AaBbCc and AaBbCc Lethal Genes: An allele that if present, results in premature death. Lethal genes can be either dominant (heterozygotes or homozygous dominant will be affected) or recessive (only homozygous recessive will die). 17.

- There is an autosomal gene in cats that controls whether or not they also have white patches of fur (W = white spots, w= no white spots). Considering this along with the Orange gene (O0 and OB) from the previous question, and how it works, how many possible genotypes (using these 4 alleles) are there for cats that are orange, black, and white (in other words, calico)?arrow_forwardWhat does Mendel’s law ofsegregation tell us about chromosomalinheritance?arrow_forwardWhy do unrelated children with a disorder such as Down syndrome resemble each other more closely than they do their siblings?arrow_forward

Would the twins risk decrease if he were raised in an environment different from that of his schizophrenic brother?arrow_forwardFor Mendelian inheritance, the nuclear genotype (i.e., the allelesfound on chromosomes in the cell nucleus) directly influences anoffspring’s traits. In contrast, for non-Mendelian inheritance patterns, the offspring’s phenotype cannot be reliably predicted solelyfrom its genotype. For the following traits, what do you need toknow to predict the phenotypic outcome?A. Dwarfism due to a mutant Igf2 alleleB. Snail coiling directionC. Leber hereditary optic neuropathyarrow_forwardIn the 1800s, a man with dwarfism who lived in Utah produced a large number of descendants: 22 children, 49 grandchildren, and 250 greatgrandchildren (see the illustration of a family pedigree to the right), many of whom also exhibited dwarfism (F. F. Stephens. 1943. Journal of Heredity 34:229–235). The type of dwarfism found in this family is called Schmid-type metaphyseal chondrodysplasia, although it was originally thought to be achondroplastic dwarfism. Among the families of this kindred, dwarfism appeared only in members who had one parent with dwarfism. When one parent exhibited dwarfism, the following numbers of children were produced. Q. Use chi-square tests to determine if the numbers of children with each phenotype in family C (1 with normal stature, 6 with dwarfism) and in family D (6 with normal stature, 2 with dwarfism) are significantlydifferent from the numbers expected on the basis of your proposed mode of inheritance. How would you explain these deviations from the…arrow_forward

Although each colormay breed true, many different outcomes occur if numerous littersare examined from a variety of matings, where the parentsare not necessarily true-breeding. The following results showsome of the possibilities. Propose a mode of inheritance that isconsistent with these data, and indicate the corresponding genotypesof the parents in each mating. Indicate as well the genotypesof dogs that breed true for each color.(a) black * brown ¡ all black(b) black * brown ¡ 1/2 black1/2 brown(c) black * brown ¡ 3/4 black1/4 golden(d) black * golden ¡ all black(e) black * golden ¡ 4/8 golden3/8 black1/8 brown(f) black * golden ¡ 2/4 golden1/4 black1/4 brown(g) brown * brown ¡ 3/4 brown1/4 golden(h) black * black ¡ 9/16 black4/16 golden3/16 brownarrow_forwardWhat is the mode of inheritance of this pedigree and why?arrow_forward
