Genetics: Reproduction

TermDefinition
Gamete A reproductive cell having a single set of chromosomes, Such as a mature sperm or egg.
Budding Asexual reproduction in which a part of an organism breaks off and becomes a new organism
Mutation A change in the DNA sequence that make up a gene
Sex linked trait A trait that is determined by the sex chromosomes of an organism.
Selective breeding The process of reproducing plants and animals so that a desirable trait is carried into future generations.
Genetic engineering The process of transferring genes from one organism to another to produce a desirable trait.
Diploid Having a pair of each type of chromosome so that the basic chromosome number is doubled.
Haploid Having a single set of chromosomes.
Meiosis The process of cell division in sexually reproducing organisms that reduces the number of chromosomes in reproductive cells from diploid to haploid, leading to the production of gametes in animals and spores in plants.
Mitosis The process by which the nucleus divides, typically consisting of four stages, prophase, metaphase, anaphase, and telophase; resulting in two new nuclei, each of which contains a complete copy of the parental chromosomes.
Autosome A chromosome that is not a sex chromosome.
Sex chromosomes Either of a pair of chromosomes, usually designated X or Y, in the germ cells of most animals and some plants, that combine to determine the sex and sex-linked characteristics of an individual, with XX resulting in a female and XY in a male in mammals.
Homologous chromosome A pair of chromosomes, one inherited from each parent, that have corresponding gene sequences and that pair during meiosis
Ovum The female reproductive cell of animals; egg.
Oogenesis The formation, development, and maturation of the female gamete (egg) by meiosis.
Spermatogenesis Formation and development of male gamete (sperm) by meiosis.
Trisomy The condition of having three copies of a given chromosome in each somatic cell, rather than the normal number of two.
Monosomy A chromosome having no homologue, especially an unpaired X-chromosome.
Karyotype The characterization of the chromosomal complement of an individual or a species, including number, form, and size of the chromosomes.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
