Advanced Genetics

QuestionAnswer
Single gene trait WW, Ww, ww
Intermediate traits Phenotype that is between the dominant and recessive phenotypes; Human male voices: bass, baritone, tenor
Multiple Alleles More than two alleles that code for a trait; human blood types (A, B, O)
Multiple Genes Results in a larger variety of phenotypes for a specific trait; example: AABbccDd
Sex-Linked Traits Genes carried on X chromosome; more common in males due to only having 1 X allele
Genotype for Males XY
Genotype for Females XX
Asexual Reproduction Results in an identical offspring and limited genetically diverse population
Sexual Reproduction Results in a genetically different offspring and genetically diverse populations
Asexual Reproduction Methods Binary Fission, Budding, Mitosis, Spores, Propagation, Cloning
Sexual Reproduction Methods Conjugation, Gametes, Pollination
Cystic Fibrosis Thick mucus production in lungs and intestines that causes breathing and digestion difficulties; mutation on recessive allele; no cure
Sickle Cell Disease Irregularly shaped red blood cells that carry limited amounts of oxygen; no cure
Hemophilia Bleeding disorder that decreases a person's ability to clot blood; recessive sex-link trait carried on X chromosome
Down's Syndrome Three chromosome #21 resulting in varying levels of mental retardation
Huntington's Disease Degeneration or breakdown of brain cells; mutation carried on a dominant allele
Carrier Person that carries the gene for a trait but does not show symptoms of the disorder; heterozygous genotype
Hybridization The crossing of two genetically different organisms in order to get the best traits from each parent
Inbreeding The crossing of two genetically similar organisms(similar alleles) in order to get the keep preferred traits
Cloning Produces offspring that is genetically identical to the parent
Genetic Engineering The transfer of genetic material from one organism into another organism in order to produce a specific trait
Selective Breeding The purposeful breeding by humans of two organisms with desired traits in order to get specific traits in offspring.
What is the probability of getting a child with O blood type if mom is heterozygous A and dad is heterozygous B blood types? 25%
What is the probability of getting a child with A blood type if mom is homozygous A and dad is heterozygous B? 50%
Huntington's Disease is carried on a dominant allele. If dad does not have the disease and mom is heterozygous for the disease, what are the odds of them having a child with Huntington's Disease? 50%
Huntington's Disease is carried on a dominant allele. If dad is homozygous for the disease and mom does not have the disease, what are the odds of them having a child with Huntington's Disease? 100%
Cystic Fibrosis is a genetic disorder carried on a recessive allele. If mom and dad are both carriers for the disorder, what are the odds of them having a child with the disorder? 25%
Cystic Fibrosis is a genetic disorder carried on a recessive allele. If mom and dad are both carriers for the disorder, what are the odds of them having a child that is heterozygous for the disorder? 50%
Cystic Fibrosis is a genetic disorder carried on a recessive allele. If mom is heterozygous for the disorder and dad does not carry the gene, what are the odds of them having a child with the disorder? 0%
Cystic Fibrosis is a genetic disorder carried on a recessive allele. If mom is heterozygous for the disorder and dad does not carry the gene, what are the odds of them having a carrier for the disorder? 50%

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.
