● 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...

In the 1850s and 1860s, Mendel bred pea plants and examined the way that traits were passed down across generations. His conclusions, although not accepted during his lifetime established the foundation for the field of genetics. What is the most relevant summary of these conclusions? The hereditary factors responsible for traits such as shape and flower color are inherited as discrete units. The purple flower of the F1 offspring of Mendel's parental generation crosses indicate that: both a an...

The process of DNA replication requires that each of the parental DNA strands be used as a _____ to produce a duplicate of the opposing strand - CORRECT ANSWER-(c) template DNA replication is considered semiconservative because - CORRECT ANSWER-(c) each daughter DNA molecule consists of one strand from the parents DNA molecules and one new strand (d) true, but not correct - new DNA strands must be copied from a DNA template The classic experiments conducted by Meselson and Stahl demons...

Genetics final exam prep, (Answered) With Complete Verified Solutions 1. Place the steps of generating a gene - knockout mouse in order from the dis- ruption of the target gene to generat- ing homozygous knockouts. Suppose in 1. Disrupt target gene by insert- ing neo+ and link tk+ to disrupted gene 2. transfer disrupted gene into one experiment, the stem cells used are stem cells from a black mouse from a black coated mouse, and the earl3y. allow recombination with mouse embryo ...

Autosome—any chromosome not considered as a sex chromosome, or is not involved in sex determination (occurs in somatic cells) Bivalent—a pair of homologous chromosomes in synapsis during meiosis Drosophila melanogaster—a species of fruit fly used in genetics because of the large size of its chromosomes epistasis (gene x gene interaction)—interaction between nonallelic genes at two or more loci resulting in one gene masking the phenotypic expression of another gene x environment in...
