In a parental cross of a ADHL disease trait, where the father is affected and the mother is unaffected, 50% of the offspring will have the disease phenotype and 50% will have the WT phenotype. In an F₁ cross between an unaffected male and an unaffected female, the respective expected proportions of the disease phenotype and WT phenotype in the F2 generation are: 1.0 and 0.0. 0 and 1.0. X 0.75 and 0.25. 0.50 and 0.50. 0.667 and 0.333.

Individuals of genotype AaBb were mated to individuals of genotype aabb. One thousand offspring were counted, with the following results: 474 Aabb, 480 aaBb, 20 AaBb, and 26 aabb. What type of cross is it? Are these loci linked? What are the two parental classes and the two recombinant classes of offspring? What is the percentage of recombination between these two loci? How many map units apart are they?
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
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?
Sunflowers with flowers 10 cm in diameter are crossed with a plant that has 20-cm flowers. The F1 plants have flowers 15 cm in diameter. In the F2 generation, 4 flowers are 10 cm in diameter and 4 are 20 cm in diameter. Between these are 5 phenotypic classes with diameters intermediate to those at the extremes. a. Assuming that the alleles that contribute to flower diameter act additively, how many genes control flower size in this strain of sunflowers? b. How much does each additive allele contribute to flower diameter? c. What size flower makes up the largest phenotypic class?

In a parental cross of a ADHL disease trait, where the father is affected and the mother is unaffected, 50% of the offspring will have the disease phenotype and 50% will have the WT phenotype. In an F1 cross between an affected male and an unaffected female, the expected proportions of the Disease Phenotype and the WT phenotype, respectively, are: a. 0.667 and 0.333. b. 0.50 and 0.50. c. 0.333 and 0.667. d. 0.0 and 1.0 e. 0.75 and 0.25.
In a parental cross of a autosomal dominant homozygous lethal disease trait, where the father is affected and mother unaffected, 50% of offspring will have disease phenotype and 50% will have the wild type phenotype.
