Bio 235 Exam II Questions With 100% Correct Answers Complementary Gene Action Genes working in tandem to produce a particular trait. Duplicate Recessive Epistasis 9:7 ratio, either allele can mask another hypostatic gene's expression. Complementation Mutation in both genes work together to produce a different expected phenotype. Noncomplementation Mutations occur in the same gene to produce the same phenotype. When do two genes assort independently? When they are located on different...

Genetics 3333 Exam 3 Thompson Questions with Answers less than needed for x - Answer-Suppose that the dan from bacterial species y was shown to contain 15% guanine relative to the dan for species x. the amount of energy necessary to completely dissociate species y dan into tow sing strands would be: d - Answer-Polytene chromosomes: -contain chromosome arms that can be distinguished without specializing g banding b- contains hundreds of replicated dan strands c- contain heterochroamin that m...

Natural Selection the process that results in adaptation of a population to the biotic and abiotic environments. Polygenic controlled by more than one pair of alleles located at different gene loci Directional Selection occurs when an extreme phenotype is favored and the distribution curve shifts in that direction. Example: resistance to antibiotics and pesticides Stabilizing Selection Occurs when an intermediate phenotype is favored. Individuals near the average are fav...

define one genetic map unit ~ the physical distance between two genes that results in a 1% frequency of recombination In birds, sex is determined by ZW chromosome inheritance. Males are ZZ and females are ZW. Within pigeon populations there is a recessive, Z-linked allele that is lethal in embryos. What is the expected sex ratio in the offspring of a cross between a male that is heterozygous for the lethal allele and a wildtype female? ~ 2:1 male to female A recessive allele on the X c...

binary fission - asexual, usually in prokaryotes origin (of replication) - bidirectional (replication AND separation together) homologous chromosome (homologue) - one from mom, one from dad; similar not identical; same alleles in the same order chromatid; sister chromatid - two IDENTICAL halves of a single replicated eukaryotic chromosome histone - proteins that have DNA wrapped around them in the *nucleosome* structure nucleosome - 147nt of DNA wrapped around a core of 8 histone proteins ...

● Autosome: ○ Any chromosome not considered as a sex chromosome, or is not involved in sex determination. ○ It occurs in pairs in somatic cells and singly in sex cells (gametes) ● Bivalent: ○ a pair of homologous chromosomes. ● Drosophila melanogaster: ○ a species of fruit Fly much used in genetics because of the large size of its chromosomes. ● Epistasis (gene x gene interaction): ○ refers to genetic interactions in which one gene modifies the effects of another gen...
