The P gene controls spotting patterns in cats. PP cats are spotted, but pp cats are not. A PP cat and a pp cat are mated, and the offspring have a few spots, but not as many as the spotted parent. Write this cross out phenotypically Add the genotypes What is the genotype of the offspring? What is this inheritance an example of?

J. A. Moore investigated the inheritance of spotting patterns in leopard frogs (J. A. Moore. 1943. Journal of Heredity 34:3–7). The pipiens phenotype had the normal spots that give leopard frogs their name. In contrast, the burnsi phenotype lacked spots on its back. Moore carried out the following crosses, producing the progeny indicated. Parent phenotypes: Progeny phenotypes burnsi × burnsi 39 burnsi, 6 pipiens burnsi × pipiens 23 burnsi, 33 pipiens burnsi × pipiens 196 burnsi, 210 pipiens a. On...

Some cats (commonly referred to as "tuxedo cats") exhibit white spotting patterns on their fur. This white spotting trait is controlled by a single gene (S). Three phenotypes are possible for cats based on their genotype at the S locus. SS results in high grades of white spotting (white) cats. Ss results in medium grades of white spotting (tuxedo) cats. ss results in solid colored cats with no spotting. You are studying an isolated population of cats where a certain...

Mendelian Genetics The gene involved in the disease Sickle Cell Anemia (SCA) is on human chromosome 11. Allele “A” is the normal form of the gene and codes for a part of the protein complex called hemoglobin. Hemoglobin is required for your blood cells to carry oxygen. Allele “a” is an abnormal form of the gene. The hemoglobin protein made from the “a” allele is defective. Red blood cells containing the defective protein are very fragile. This disease is recessive–meaning...

1. In cats, two unlinked genes control coat coloration: D, an autosomal gene, causes fur to be black (D/-) or brown (d/d). Black is the wildtype and brown is caused by a mutation E, an X-linked gene, causes white fur and is dominantly epistatic to D. (Write as XE or Xe). A pure-breeding white male cat is mated with a pure-breeding brown female cat. A. What are the genotypes of the parents? what phenotypic ratio is expected in the F17(Rem...

5. In Mendel's experiments, the pod color gene and the seed shape gene were located on different chromosomes (in other words, they were not linked. They assort independently). Green pods (G) are dominant over yellow pods (g) and tall stems (T) are dominant over dwarf stems (t). You are given two true breeding plants (homozygous at both genes). In the parental (P) generation, one parent has green pods and dwarf stems and the second parent has yellow pods and tall...
