As it turned out, one of the tallest Potsdam Guards had an unquenchable attraction to short women. During his tenure as guard, he had numerous clandestine affairs. In each case, children resulted. Subsequently, some of the childrenwho had no way of knowing that they were relatedmarried and had children of their own. Assume that two pairs of genes determine height. The genotype of the 7-foot-tall Potsdam Guard was A9A9B9B9, and the genotype of all of his 5-foot clandestine lovers was AABB. An A9 or B9 allele in the offspring each adds 6 inches to the base height of 5 feet conferred by the AABB genotype. a. What were the genotypes and phenotypes of all the F1 children? b. Diagram the cross between the F1 offspring, and give all possible genotypes and phenotypes of the F2 progeny
A pedigree analysis was performed on the family of a man with schizophrenia. Based on the known concordance statistics, would his MZ twin be at high risk for the disease? Would the twins risk decrease if he were raised in an environment different from that of his schizophrenic brother?
Given a cross between these two parents: BbCcDDEEFfGgHhJj x BbCcddEeFfGgHHjj where traits B, E, H, J exhibit Mendelian inheritance; C, and F exhibit incomplete dominance; D, and G exhibit co-dominance answer the following: How many possible gametes can the first individual produce? What proportion of the offspring will phenotypically resemble the first parent? What proportion of the offspring will genotypically resemble the second parent? How many phenotypes can be expected from the cross?

In earlobes, free (F) earlobe is dominant while attached (f) earlobe is recessive. What proportion of the offspirng would we expect to have attached earlobes in the following crosses: 1. Heterozygous dominant for ree earlobes with homozygous dominant for free earlobes. ______ 2. Homozygous dominant for free earlobes with attached earlobes. ______ 3. Attached earlobes with attached earlobes. (Answer in percent) ______
Use Punnett Square:The letter that accompanies each trait is representative of the dominant allele. This is the letter you will use when recording the genotypic information for each trait.Read through the descriptions of each trait and determine which phenotype you express. Record your phenotypeNext, determine your genotype. If you express the dominant phenotype, you cannot determine the second allele you carry, so you must list the two possible genotypes. Record this. Question: Widow’s Peak (W): A hairline that forms a downward point in the middle of the forehead is caused by a dominant allele. A smooth hairline is caused by a recessive genotype.
Given a cross between these two parents: BbCcDDEEFfGgHhjj x BbCcddEeFfGgHHjj where traits B, E, H, J exhibit Mendelian inheritance; C, and F exhibit incomplete dominance; D, and G exhibit co-dominance answer the following: What proportion of the offspring will genotypically resemble the second parent?
Which of the following traits are complete dominance, incomplete dominance, X-linked, or sex-linked? Tongue Rolling (R or r) Cleft Chin (V or v)Dimpled Cheeks (G or g)Widow's Peak (W or w) Lobed Ears (L or l)Hair Form (C or C') Red Hair (T or t)Dominant Eye (E or e)Index vs. Ring Finger (F or F')Hitchhiker's Thumb (N or n)Arm Folding (A or a)

Question: Eye color (B): Inheritance of eye color is controlled by multiple genes, but people having the homozygous recessive genotype have blue eyes. People who have a dominant allele may have different shades of brown, hazel, or green eyes.
