| Tutor | Hello Tricia, Welcome to tutorvista! |
| Tutor | I'm Susan your Bio tutor for today. |
| Student | Ok hello |
| Tutor | I've seen the document |
| Student | this is what i need help with today |
| Student | can you help me? |
| Tutor | ok |
| Tutor | which quest. do we begin with |
| Student | you see were it says step 1? |
| Tutor | yes |
| Student | thats were we start |
| Tutor | Do u understand the terms homozygous |
| Student | yes they mean the same like PP or pp right? |
| Tutor | genotypes etc |
| Tutor | correct |
| Student | do you see were it says step 2? |
| Tutor | here - it doesnt show |
| Student | huh i dnt see the hole work sheet that i was supposed to have sent u...... |
| Tutor | its ok |
| Student | huh i dnt understand |
| Tutor | I have the earlier one u sent |
| Student | it has all of them step one and 2? |
| Tutor | one u uploaded before |
| Tutor | shows step 2 |
| Student | ok good well lets get started i need help wit stpe 1 |
| Student | so were it says parent 1 and under neath it says genotype.. what would i put there? |
| Tutor | genotype parent1- PP |
| Student | so for the genotype of parent one it would be PP? |
| Tutor | yes |
| Student | so the phenotype would be Pp? |
| Tutor | Phenotype parent1- purple flower plant |
| Tutor | Phenotype means the observable characteristics |
| Tutor | the colour , shape etc |
| Student | oh thanks i didnt kno that |
| Tutor | genotype parent 2- pp |
| Tutor | so what wld this phenotype |
| Student | and parent 2 phenotype would be white flower plant right? |
| Tutor | absolutely right |
| Tutor | there is only one type of allele in parent1 |
| Student | so what would i put for the answer How many alleles are in the sex cell of parent1? |
| Student | 2 right? |
| Student | how i dnt get it |
| Tutor | there are 2 alleles but they are both the same type |
| Tutor | P allele |
| Tutor | ok? |
| Student | oh so it would be 1 allele for parent 1 and 2 right? |
| Tutor | In parent 2- also there are 2 alleles but they are the same type -p |
| Tutor | see the WB |
| Student | so how many sex cells? 1 or 2? |
| Student | yes i see wb but i dnt see you putting anything there |
| Tutor | now can u see |
| Student | yes |
| Student | so it out be just one sex cell for pp or PP but it would be two sex cells if it waz Pp right? |
| Tutor | yes |
| Student | So now the part for the offsprings... wat would be the Genotype? |
| Student | it would be Pp right? |
| Student | ok |
| Tutor | yes |
| Tutor | can u see the WB |
| Student | yes i can |
| Student | how about the phenotype for the offspring? |
| Student | would it be purple flower plant/white flower plant? |
| Tutor | They will be all purple flower plts |
| Student | how thou i dnt get it |
| Tutor | as purple allele P- is dominant over the recessive allele-p |
| Student | oh yea thats right thank u for reminding me |
| Tutor | yes |
| Student | ok for step 2 i did it already but u see it right i wanna see if i did it right |
| Student | for number 1 i put PP, for number 2 i put pp, for number 3 i put Pp, and for number 4 i put Pp. Is this right? |
| Student | r u there? |
| Tutor | they have given u choices like A, B, C, D |
| Tutor | that is what u have to select, right? |
| Student | yes i think you are right i didnt even see that |
| Tutor | so for the first |
| Tutor | punnett square B |
| Student | so for number one it would be B right? |
| Tutor | is the right choice |
| Tutor | yes correct |
| Student | its B right? |
| Student | and number 2 would be D right? |
| Tutor | yes correct |
| Student | now i am a lil confused about 3 and 4 |
| Tutor | Homozygous purple-PP |
| Tutor | crossed with homozy white-pp |
| Student | So A would be 3 right? |
| Tutor | no |
| Student | it would be D? |
| Tutor | check that again |
| Tutor | PP with pp |
| Student | i dnt understand why it would be D |
| Student | i mean c |
| Tutor | C is correct |
| Student | this one i am really comnfused on this one |
| Tutor | see on the WB |
| Student | why though i done understand |
| Tutor | I will explain |
| Student | yes i see it |
| Tutor | new pg |
| Student | how do i do a new page? |
| Student | i dnt see anything |
| Tutor | now u can? |
| Student | wright somthing |
| Student | yes i see it now |
| Tutor | ok |
| Tutor | PP and pp |
| Student | but c has Pp in all 4 squares |
| Tutor | did u follow what that means |
| Tutor | yes |
| Tutor | let me explain |
| Tutor | can u see one parent shown on the top |
| Student | yes |
| Tutor | and other parent alleles below |
| Student | yes |
| Tutor | so the cross between both these will give u |
| Tutor | see on the WB |
| Student | yes |
| Tutor | we are crossing the alleles of both parents |
| Student | ok so number 4 would be A? |
| Tutor | yes |
| Tutor | what iyour answer for 3rd |
| Student | for number 3? |
| Tutor | yes |
| Student | C |
| Tutor | yes good |
| Tutor | did u follow how? |
| Student | so #1 would be B, #2 would be D, #3 would be C, and #4 would be A? |
| Student | yes i see how now |
| Tutor | yes good thats right |
| Tutor | so its getting easier |
| Tutor | YES? |
| Student | yes thanks so now i have to do the vocab break |
| Student | do u c the vocab break? |
| Tutor | Difference betwn monohybrid and dihybrid cross? |
| Student | yes |
| Student | i dnt kno wat eather things are |
| Tutor | Its very simple |
| Tutor | I will tellu |
| Student | ok thanks |
| Student | ok |
| Tutor | Monohybrid cross- is what we were |
| Tutor | doing just now |
| Tutor | all the punnett squares that u see in the previousuest |
| Tutor | previous question |
| Student | ok now wat is dihybrid cross? |
| Tutor | I will put up the definition on the WB |
| Student | thanks |
| Tutor | for monohybrid |
| Student | so wat is the deffitions for dihybrid cross |
| Tutor | Dihybrid - the word DI- means TWO |
| Tutor | MONO means -ONE |
| Tutor | can u see the definitions |
| Tutor | and their difference |
| Student | yes but i dnt kno how to put it in a sentence |
| Tutor | u write the 2 definitions down |
| Tutor | and highlight what i have underlined |
| Tutor | as the difference |
| Tutor | see the last punnett square with 16 small squares |
| Tutor | that is the example of a dihybrid cross |
| Tutor | When we studied only the flower colour- purple /white |
| Tutor | that is ONE PAIR of contrasting traits |
| Tutor | yes? |
| Student | what i put down was "the difference between monohybrid and dihybrid crosses are mono is one pair of contrasting traits and dihybrid is two pairs of contrasting traits. am i right? |
| Tutor | Yes a cross that studies the inheritance of ONE /TWO Pairs of contrasting traits |
| Tutor | DID u follow that? |
| Student | yes i did thank you |
| Tutor | Anything else |
| Student | now there is another side that i scaned and i have it on my computer how would i send it to you? |
| Tutor | we have a couple of mins more |
| Student | can i go scedual another session at 2? |
| Student | wit u? |
| Tutor | You may schedule another session |
| Student | with you? |
| Tutor | I will be available only for another hour |
