| Question | Answer |
|---|---|
| ONE SPECIES DIFFER FROM ANOTHER CALLED à | INTERSPECIFIC VARIATION |
| SAME SPECIES DIFFER FROM EACH OTHER | CALLED INTRASPECIFIC VARIATION. TWINS SAME DNA. |
| REPRESENTATIVE OF THE POPULATION / | RELIABLE).SAMPLING BIAS CHANCE |
| ELIMINATE SAMPLING BIAS/ ELIMINATE | HUMAN INVOLVEMENT. RANDOM (SAMPLING). |
| THE GREATER THE SAMPLE | SIZE THE MORE RELIABLE. |
| TEST ALLOW US TO DECIDE | WHETHER ANY VARIATION OBSERVED DUE TO CHANCE OR OTHER. |
| VARIATION CAUSED BY – GENETIC | , ENVIRONMENTAL/BOTH |
| GENETIC DEFENCES DIFF IN GENES. | DIFFERENCES CHANGE FROM GENERATION TO GENERATION. |
| GENETIC VARIATION | CAUSED BY MUTATIONS: |
| RNADOM CHNAGES TO GENE | AND CHROM MAY ,OR MAY NOT BE PASSED ON TO NEXT GENERATION. |
| MEIOSIS – NUCLEAR DIVISION FORMS | THE GAMETES. MIXES UP/ GENETIC INFO COZ IT PASSED DIFF GAMETES. |
| FUSION OF GAMETES – | IN SEXUAL REPRODUCTION. OFFSPRING INHERIT / CHARACTERISTICS OF EACH PARENT |
| FUSION GAMETES FERTILISATION | IS RANDOM PROCESS . CREATE VARIETY OF OFFSPRING. |
| VARIETY IN ASEXUAL | REPRODUCTION VIA MUTATION . |
| POULATION OF SEXUAL | REPRO MORE VARIED. |
| ENVIRONMENTAL INFLUENCE | AFFECT THE WAY GENES ARE EXPRESSED. |
| THE GENES SET LIMITS BUT THE | ENVIRONMENT DETERMINES WHERE LIMITS LIES. |
| PLANT HAVE TALL GENE , SEED | GERMINATION, POOR LIGHT AND LOW SOIL NITROGEN. PLANT SHORT. |
| ENVIRONMENTAL INFLUENCE ARE | / CLIMATIC CONDITIONS. |
| (E.G. TEMP , RAINFALL , SUNLIGHT) | /SOIL CONDITIONS, PH, FOOD AVAILABILITY. |
| BLOOD GROUP CONTROLLED | BY SINGLE GENE.PIE CHART. |
| CONTINUUM. – CAHARCTERISTIC | JOIN TOGETEHR :HEIGHT AND MASS. |
| (POLYGENE'S) CONTROL | HEIGHT MASS. |
| A BELL SHAPED CURVE – | NORMAL DISTRIBUTION CURVE. |
| SHOW S NUMBER OF PEOPLE | IN A PARTICULAR SAMPLE WITH DIFF HEIGHTS. |
| STANDARD DEVIATION= THE SQUARE ROOT OF THE SUM | OF THE MEASURE VALUE – THE MEAN VALUE^2 / THE TOTAL NUMBER ROOF VALUES IN THE SAMPLE. |
| 1. CALCULATE THE MEAN 2. | SUBTRACT THE MEAN FORM EACH OF THE VALUES |
| 3. COZ SOME NEGATIVE HAVE | TO SQUARE ALL THE NUMBERS. |
| 4. ADD ALL SQUARED NUMBERS | TOGETHER. 5.DIVIDE THE TOTAL BY AMOUNT. |
| REMEMBER TO SQUARE | ROOT IN THE END. |
| DOUBLE HELIX IN | DNA RECOGNISABLE. |
| DNA DETERMINES INHERITED | CHARACTERISTICS /HAS A LOT OF INFORM/ IN FORM GENETIC CODE. |
| DNA MADE FROM : DEOXYRIBOSE, | PHOSPHATE GROUP, ORGANIC BASE. |
| CONDENSATION REACTION | BETWEEN A PHOSPHATE GROUP AND A DEOXYRIBOSE SUGAR. |
| COMBINED DUE TO | CONDENSATION REACTION /(MONONUCLEOTIDE |
| LONG CHAIN MONO | NUCLEOTIDE POLYNUCLEOTIDE. |
| SINGLE RING BASES – | CYTOSINE AND THYMINE. |
| DOUBLE RING BASES – | ADENINE AND GUANINE. |
| DNA MADE OF 2 STRANDS | OF NUCLEOTIDES ,(POLYNUCLEOTIDE'S.) |
| EACH 2 STRANDS LONG, AND | JOINED BY HYDROGEN BONDS / BETWEEN BASES. |
