There Are Organisms That Go Through Meiosis but Do Not

question 61

Multiple Choice

There are organisms that go through meiosis but do not undergo recombination when forming haploid gametes.Which of the following statements correctly describes the gametes produced by such an organism? (Assume that these organisms are diploid, that each of the two homologous chromosomes are genetically distinct as typically found in the wild, and that these organisms have more than one chromosome.)

• A)All gametes formed during a single meiosis will be identical.
• B)Due to the random assortment of homologs, each of the gametes formed during a single meiosis will be different.
• C)This organism could potentially produce 2ⁿ genetically distinct gametes, where n is its haploid number of chromosomes.
• D)The fusion of any two gametes produced by such an organism that does not undergo recombination during meiosis will create a cell that is genetically identical to that individual.

Definitions:

Postreinforcement Pause

A cessation of behavior following reinforcement on a ratio schedule, which is followed by resumption of responding at the intensity characteristic of that ratio schedule.

Behavioral Contrast

The phenomenon where the rate of response to one stimulus changes as a consequence of a change in reinforcement conditions for another stimulus.

Variable-Interval Schedule

A Variable-Interval Schedule is a type of reinforcement schedule where responses are reinforced after varying intervals of time, making the reinforcement unpredictable.

Primary Reinforcement

A reinforcer that satisfies a basic biological need, such as food, water, or sleep, and is inherently rewarding.
