QuestionAnswer
Petunias that are pink from red and white parents are an example of _Incomplete__ dominance where neither allele is dominant.
Chickens with black and white feathers display __Codominance__ where both alleles share dominance.
The many different colors of rabbit coats are an example of __Multiple Alleles___ determining coat color and are the result of the interaction between two or more alleles.
__Polygenic_ traits are when more than one trait interacts and human eye color is an example.
Environmental conditions can also impact the genes and the butterfly is a good example. The wings are light colored when the temperature is high as in _Summer___ and dark when the temperature is low as in fall.
Genes that occur very close together on a chromosome are said to be linked
The purpose of meiosis is to half the genetic information
Duplicated chromosomes are called __Homologous__.
During prophase I of meiosis the homologous chromosomes pair up to form a Tetrad
Crossing over occurs during ___Prophase I__ of meiosis.
The cells become haploid during __Telophase I__ of meiosis.
At the end of meiosis II there are four identical/unique haploid cells. Unique
A situation in which a gene has more than two alleles is known as Multiple Alleles
A pink-flowered Mirabilis plant (RW) is crossed white a white-flowered Mirabilis (WW). What is the chance that a seed from this cross will produce a red-flowered plant? 0
The illustration below represents what stage of meiosis? metaphase 1
Unlike mitosis, meiosis in male mammals results in the formation of four haploid gametes
Gene map The relative locations of genes on a chromosome
Suppose that an organism has the diploid number 2N=8. How many chromosomes do this organism's gametes contain? 4 chromosomes.
What happens to the chromosome number during meiosis? It halves
During which phase of meiosis is the chromosome number reduced? anaphase 1
Two pink-flowering plants are crossed. The offspring flower as follows: 25% red, 25% white, and 50% pink. What pattern of inheritance does flower color in these flowers follow? Incomplete dominance
Which of the following is used to construct a gene map? Recombination rate
Alleles for the same trait are separated from each other during the process of Meiosis 1
How many map units apart are genes A and D? 8
Which gene map best reflects the student's data? D. C B A D

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.
