AP Biology Unit 5 Vocabulary - Cruz-Matias

TermDefinition
Chromosomes cellular structure carrying genetic info
Daughter Cell clones of parent cells
Diploid (2n) 2 full sets of chromosomes
Gamete sex cells
Haploid (n) 1 set of chromosomes
Meiosis results in 4 haploid daughter cells, sex cells
Chromatid single chromosomes
Crossing Over chromosomes exchange segments, results in recombinant chromatids
Fertilization union of haploid gametes to produce a diploid zygote
Homologous Chromosomes pair of chromosomes of the same length, centromere position, and staining pattern that possess genes for the same characters at corresponding loci
Sexual Reproduction two parents make offspring , that have combination of genes inherited from parents
Allele specific variation of gene
Conserved yes
Genotype combination of inherited genes
Law of Independent Assortment alleles for separate traits are packaged in every possible combination into gametes
Law of Segregation when chromosomes separate during meiosis so do alleles, shows genetic variation among gametes
Phenotype physical result of genotype
Trait genetically determined characteristic of an organism
Zygote diploid cell produced by union of haploid gametes during fertilization
Genetic Linkage genes that are adjacent and close to each other on same chromosome and that are inherited together
Sex-Linked Trait traits that are determined by genes located on sex chromosomes
Nondisjunction occurs when chromosomes do not separate properly during cell division

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.
