Biology #11

TermDefinition
Gregor Mendel Formulated particulate theory of inheritance in the 1860s via pea plants
Blending of concept inheritance Variation decreased as ppl are more like their traits, reshuffling of genes from generation to generation
Particulate Theory of Inheritance Idea that traits are inherited as genes that separate across generations rather than blending together
Points of the Theory of Inheritance Traits controlled by (genes) passed on from parent to offspring, genes come in different versions called alleles, individuals inherit two alleles for each trait (one from each parent), alleles don't blend - they remain distinct, traits can skip generation
Monohybrid Cross Varieties that differed only one trait. (true -breeding ((homozygous)) plants)
Law of Segregation Individuals have one pair of alleles per trait. Alleles segregate during gamete formation. Each gamete contains one factor from each allele. Fertilization gives offspring two factors for each trait
Dominant allele Shows its effect even if there is only one copy (over a recessive trait)
Recessive allele Only apparent if you get two copies, one from each parent. Dominant always overwrites
Gene Locus Specific location of a gene on a chromosome
Homozygous Identical alleles
Heterozygous Different alleles
Genotype Two alleles an individual has for a specific trait. Identical = homo different = hetero
Phenotype Physical appearance of the individual
Law of Dominance When two different alleles are inherited, the dominant allele will always mask the recessive one,
Law of Independent Assortment Genes for different traits are passed on independently of each other when gametes are formed
Dihybrid cross True breeding plants differing in two traits
Law of Probability The chance of inheriting a specific allele or trait, typically using punnett squares
Sum rule Allows us to add the genotypes that produce the identical phenotype to find out the chance of a particular phenotype
Testcross Determines the genotype of an individual having the dominant phenotype
Autosome Any chromosome other than a sex chromosome (X,Y)
Codominance Both alleles are fully expressed in the phenotype, they both show up at the same time. (AB blood)
Incomplete Dominance Neither allele is dominant, blending together. (red + white = pink)
Incomplete Penetrance Not everyone who inherits a mutated gene actually shows symptoms, but they do have it
Pleiotropy Single mutant gene affects two or more distinct and seemingly unrelated traits
Polygenetic Inheritance When multiple genes worth together to determine a single trait. (Height, skin/eye color, hair texture)
X & Y chromosomes Gender chromosomes, XX = female XY = male
X-linked Carried on the X-chromosome - genes that have nothing to do with biological sex
X-linked Disorders Colorblindness, Menkes, Muscular Dystrophy, Adrenoleukodystrophy,

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.
