Information demonstrate below are SNP genotypes of Guinea hogs from Kizzi Roberts’ research project. In each cell “1” codes for one homozygote (TT for example), “-1” for the other homozygote (AA for example), and “0” for a heterozygote (AT for example). A “u” means that the genotyping reaction failed and […]

Q1. A mutation in DNA generates a UGA stop codon in the middle of the RNA coding for a particular protein. A second mutation in the cell leads to a single nucleotide modify in a tRNA that allows the correct translation of the protein. The altered tRNA translates the UGA […]

Genetics with Drosophila melanogaster lab Assignment Pre-Lab Assignment Q1. Several weeks ago, a homozygous wild-type (winged) strain of flies was crossed with a homozygous apterous (wingless) strain of flies. Using standard genetic notation, this cross can be represented as ap+/ap+ × ap/ ap. The F1 progeny of this cross were […]
