Inheritance

QuestionAnswer
the passage of traits from parent to offspring heredity
the study of the processes by which traits are passed from one generation to another genetics
the genetic makeup of an individual made of 2 alleles genotype
the expression of the genotype of an individual; the physical characteristics of an organism phenotype
the term used to refer to a genotype that has two identical alleles for a particular trait homozygous
the term used to refer to a genotype that has two different alleles for a particular trait heterozygous
one of a number of different forms of a trait allele
the offspring of crosses between parents that have different traits hybrid
organisms that will produce offspring identical to themselves when allowed to self pollinate pure breeding
describes traits that always express/show themselves dominance
describes traits that only express themselves when paired with 2 similar alleles recessive
he separation of 2 alleles during the production of alleles by meiosis segregationt
the process of division by which gametes are produced that have 1/2 the number of chromosomes meiosis
used to predict and compare the offspring produced by a designated cross/mating Punnet squares
genes for different traits separate independently during the formation of gametes by meiosis independent assortment
blending of the traits of a heterozygous genotype incomplete dominance
form of inheritance in which both alleles of a genotype are expressed equally to produce a phenotype codominance
gene that have not 2 but 3 forms of the alleles, example: blood type multiple alleles
traits that are controlled by 2 or more genes polygenic
a single gene controls the expression of many phenotypic traits pleiotrophy
source of genetic variation caused by the unlimited number of possible sperm & egg combinations random fertilization
the exchange of chromosome segments during prophase I of meiosis that causes genetic recombination crossing over
pairs of chromosomes that are similar in structure and genetic makeup, one of which is comes from the mother while the other is derived from the father homologous
the condition where genes for different traits are carried on the same chromosome linkage

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.
