This is an MCQ-based quiz for GRE on the topic of Inheritance.
This includes Autosomal Dominant Inheritance, Autosomal Recessive Inheritance, X-linked Inheritance, and Complex Inheritance.
What type of prokaryotic genetic recombination requires the presence of plasmids?
Which recombinant process depends on a F factor plasmid?
Frederick Griffith"s experiments showed that formerly harmless IIR bacteria had become deadly in mice. This change took place when the harmless IIR bacteria were exposed to the remains of heat killed IIIS bacteria. Based on this experiment, what was the process that converted the harmless bacteria to a deadly strain?
Which answer choice correctly pairs the mode of bacterial genetic transfer with its definition?
A scientist is working with a breed of dog and has noticed that two traits, ear length and color, behave in normal dominant-recessive hierarchies. Long ears (A) are dominant to short ears (a) and black coloration (B) is dominant to yellow coloration (b). If he breeds a long eared, black dog (AaBb) with a short eared yellow dog (aabb), what would be the resulting phenotypic ratios of the offspring?
Which of the following inheritance patterns only requires a single copy of a mutant allele for presentation of a specific gene disorder?
Which of the following statements about autosomal-dominant disorders is false?
Two parents are heterozygous for an allele that determines hair color for this species. These parents have offspring with the following genotypic ratios: 50% Bb, 25% BB, 25% bb The B allele produces black hair, and the b allele produces white hair. However, the phenotypic expression of this gene"s traits do not follow Mendelian patterns. If allele B exhibits incomplete dominance, which of the following is true for the offspring?
Which of the following is false about conjugation?
I. It is a form of sexual reproduction
II. It forms a bridge between two bacterial cells; the bridge is called a plasmid
III. It involves transport of genetic material via vectors
I and II
II and III

I. Potential genotype ratios of offspring
II. Possible gametes produced by parent generation
III. Allele frequencies of the population
I, II, and III
I and II
II and III
