Chapter 14 #5 A black guinea pig crossed with an albino guinea pig produces 12 black offspring. When the albino is crossed with a second black one, 7 blacks and 5 albinos are obtained. What is the best explanation for this genetic situation? Write genotypes for the parents, gametes, and offspring Answer Albino (b) is a recessive trait; black (B) is dominant. First cross: parents BB ? bb; gametes B and b; offspring all Bb (black coat). Second cross: parents bb ? Bb; gametes 1/2 B and 1/2 b (heterozygous parent) and b; offspring 1/2 Bb and 1/2 bb #6

Genetics Problems 1. A rooster with gray feathers is mated with a hen of the same phenotype. Among their offspring, 15 chicks are gray, 6 are black, and 8 are white. What is the simplest explanation for the inheritance of these colors in chickens? What offspring would you predict from the mating of a gray rooster and a black hen? 2. In some plants, a true-breeding, red-flowered strain gives all pink flowers when crossed with a white-flowered strain: RR (red) x rr (white) ---> Rr (pink). If flower position (axial or terminal) is inherited as it is in peas what will be the ratios of genotypes and phenotypes of the generation resulting from the following cross: axial-red (true-breeding) x terminal-white? What will be the ratios in the F2 generation?

Bio II DiGennaro Hardy-Weinberg Practice Problems A population of rabbits may be brown (the dominant phenotype) or white (the recessive phenotype). Brown rabbits have the genotype BB or Bb. White rabbits have the genotype bb. The frequency of the BB genotype is .35. What is the frequency of heterozygous rabbits? 0.484 What is the frequency of the B allele? 0.59 What is the frequency of the b allele? 0.41 A hypothetical population of 10,000 humans has 6840 individuals with the blood type AA, 2860 individuals with blood type AB and 300 individuals with the blood type BB. What is the frequency of each genotype in this population? AA = 0.684 / AB = 0.286 / BB = 0.03 What is the frequency of the A allele? 0.827 What is the frequency of the B allele? 0.173

Chapter 11: Complex Inheritance and Human Heredity RECESSIVE GENETIC DISORDERS -A recessive trait that is expressed when the individual is homozygous recessive for the trait CYSTIC FIBROSIS -Affects the mucus-producing glands, digestive enzymes, and sweat glands ALBINISM -Caused by altered genes, resulting in the absence of melanin in hair and eyes TAY-SACHS DISEASE -Gangliosides (fatty acids) accumulate in the brain, inflating brain nerve cells and causing mental deterioration GALACTOSEMIA -Recssive genetic disorder characterized by the inability of the body to digest galactose DOMINANT GENETIC DISORDERS -Huntington's Disease affects the nervous system -Achondroplasia is a genetic condition that causes small body size and limbs that are comparatively short
