QuestionAnswer
DNA DETERMINES .... THE CONSIDERABLE VARIETY OF PROTEINS.
SO SIMILARITIES AND DIFFERENCES DEFINES IN TERMS... OF VARIATION IN DNA . IT IS THE DIFFERENCES IN DNA.
WHAT IS A GENE ... A SECTION OF DNA THAT CODES FOR ONE OR MORE POLYPEPTIDES.
ALL MEMBERS OF SAME SPECIES HAVE SAME... GENE. ALL HUMS HAVE GENE FOR BLOOD GROUP AND ALL SNAPGARGONS HAVE GENE FOR PETAL COLOUR.
WHICH BLOOD GROUP DEPENDS ON .... 2 ALLELES OF THE GENE THE POSSES.
ORGANISM DIFFER IN THEIR ALLELES NOT... THEIR GENES.
WHAT MAKES SPECIES DIFFERENT ... IT IS THE COMBINATION OF ALLELES THAT MAKE SPECIES DIFFERENT.
THE GREATER THE NUMBER OF DIFF ALLELES THE GREATER... THE GENETIC DIVERSITY.
THE GREATER THE GENETIC DIVERSITY THE MORE LIKELY... THE SPECIES CAN ADAPT TO ENVIRONMENTAL CHANGE. COZ WIDER RANGE OF ALLELES AND WIDER RANGE OF CHARACTERISTICS.
GENETIC DIVERSITY IS REDUCED WHEN A SPECIES ... HAS FEWER DIFF ALLELES.
ARTIFICIAL SELECTION INVOLVES IDENTIFYING.... INDIVIDUALS WITH DESIRED CHARACTERISES AND USING THEM TO PARENT THE NEXT GENERATION.
IN SELCTION SO ALLELES FOR UNWANTED CHARACTERISTIC... ARE BRED OUT.
REDUCED ALLELES OVER YEARS THIS RESULTS IN ... REDUCED GENETIC DIVERSITY ONLY THE DESIRED CHARACTERISTICS.
GENETIC BREADING HAPPENS ON ... PLANTS AND DOMESTICATED ANIMALS .E.G. IN PLANTS SUCH AS WHEAT THE FEATURES SELECTED FOR INCLUDE LARGE GRAINS WITH A HIGH GLUTEN CONTENT , SHORT TERMS & RESISTANCE TO DISEASE.
THE FOUNDER AFFECT WHEN ... FEW INDIVIDUALS COLONISE A NEW REGION. THEY ONLY HAVE A SMALL AMOUNT OF ALLELES FROM THE POPULATION.
THE NEW POPULATION DEVELOPED WILL HAVE... LESS GENETIC DIVERSITY THAN OTHER.
FOUNDER AFFECT NORMALLY HAPPENS WHEN ... NEW VOLCANIC ISLANDS RISE OUT OF SEA ,MAY DEVELOPED INTO SEPERATE SPECIES AND AS FEWER ALLELES ARE ABLE TO ADAPT TO CHANGING CONDITIONS.
GENETIC BOTTLE NECKS POPULATIONS MAY DROP CAUSED BY .... NATURAL DISASTERS.
THE FEW SURVIVORS WILL HAVE... SMALLER GENETIC DIVERSITY - FEWER ALLELES.
FEWER ALLELES ... LESS GENETIC DIVERSITY –
WHOEVER FUNDS SCIENTIFIC RESEARCH... MAY HAVE INFLUENCE ON OUTCOME.

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.
