GENES |
factors that determine traites |
|
HYBRIDS |
the offspring of true breeding parents with different traits |
|
TRAITS |
Specific charachteristics that vary among individuals |
|
ALLELES |
The different forms of a gene |
|
GAMETES |
Sex cells, egg or sperm |
|
WHY ARE PEAS A GOOD MODEL SYSTEM FOR STUDYING HEREDITY? |
Because they are easy to find and they are plentifuland they are easy to breed and grow |
|
HOW DID MENDEL CROSS POLLINATE FLOWERS? |
He cross pollinated flowers by cutting of the male prts of one flower and then dusting the female parts with pollen from another flower |
|
WHAT IS THE DIFFERENCE BETWEEN A GENE AND AN ALLELE? |
A gene is factors passed to offspring and alleles are different forms of a gene |
|
STATE THE PRINCIPAL OF DOMINANCE |
Some alleles are dominant and some are recessive. |
|
WJHAT IS SEGREGATION?WHATIS THE RESULT OF SEGREGATION? |
segregation is basically seperation the result of segregation is having dfferent cells EX. sex cells blood cels etc. |
|
A BLACK CAT AND A WHITE CAT HAVE FOUR BLACK KITTENS IN F1 GENERATION. IN THE F2 GENERATION THERE ARE THREE BLACK KITTENS AND ONE WHITE KITTEN. EXPLAIN HOW THE F2 GENERATION PROVES THATT GENETIC INFORMATION PASSES UNCHANGED FROM ONE GENERATION TO THE NEXT, EVEN WHEN A SPECIFIC TRAIT IS NOT EXHIBITED. |
the F1 generation did not have any white cats but when they breed there was a white cat which is a rssecive gene |
