 called hybrids | offspring that result from crosses between true-breeding parents with different traits |
| inherited through the passing of factors from parents to offspring | mendel concluded that triats are: |
| the allele for tall plants is dominant | when mendel crossed true-breeding tall plants with true-breeding short plants, all the offspring were tall because: |
| the allele for shortness and the allele for tallness segregated when the f1 plants produced gametes | In the P generation a tall plant was crossed with a short plant. short plants reappeared in the f2 generation because |
| predict the traits of the offspring produced by genetic crosses | the principles of probability can be used to: |
| the actual results of a genetic cross | a punnett square shows all of the following except: |
| codominance | a cross of a white hen with a black rooster prodices erminette-color offspring. this type of inheritance is known as: |
| morgan chose to use fruit flies in his study cuz fruit flies produce a large amount of offspring. | which of the following statements about thomas morgan is true? |
| 6 | if an organisms diploid number is 12 what is the haploid number? |
| crossing-over | what is shown in figure 11-1? |
| prophase of meiosis 1 | chromosomes form tetrads during.. |
| 4 genetically dif. haploid cells | unlike mitosis meioisis forms..q |
| are on the same chromosome | linked genes |
| the genes are probably located close to eachother | if 2 genes are on the same chromosome and rarely assort independently, |
| the inheritance of traits | mendel used pea plants to study: |
| genes | what are mendels factors called today? |
| some alleles are dominant and some recessive | the prinicple of dominance states |
| principle of independent assortment | what principle states that during gamete formation genes for dif traits seperate w/o influencing each other's inheritance? |
| N | the # of chromosomes in a gamete is represented by the symbol.. |
