Gene tracking DNA

AS92022

QuestionAnswer
Gene tracking observing the presence/absence of a gene/allele through generations and within and between populations
Genetic variation The range of allele/allele combinations in a gene pool
The importance of genetic variation for the survival of a population in a changing environment? The greater the genetic diversity the greater the chance of individuals in the population surviving/reproducing and adapting to the change, continuing the species
Describe DNA sequencing DNA sequencing allows scientists to determine the exact order of nucleotide bases in a DNA molecule.
Describe DNA markers is a known and variable DNA sequence that can be used to identify or locate a gene of interest because it is inherited along with that gene.
describe DNA profiles Creating a unique genetic pattern by analysing multiple variable DNA regions (markers) across the genome.
how do gene sequences assess genetic diversity compare the order of bases to find how genetically similar or different individuals are, breed most different together
How do DNA sequences Assess relatedness closely related individuals share more bases, can help prevent inbreeding by avoiding pairing closely related individuals.
How do DNA sequences help ID mutations compare sequence of individuals with original phenotype and look for differences in bases.
How do Markers allow DOC to increase genetic diversity through breeding pair selection identify individuals sharing the fewest markers to create breeding pairs that are genetically different, new allele combo in offspring
How do markers track inheritance of important traits Presence of specific markers helps conservationists promote beneficial alleles and prevent harmful ones from spreading via mate choice.
How do markers ID carriers of alleles the presence or absence of known markers allow recessive alleles to be identified.

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.
