behold the punnett square...yippee

hello friends. im not even sure if we have to blog this week but im gonna cuz maybe we do i dont want to have a missing assighnment weighing down my grade. I wish this blog was worth more than like 2 points!!! D: wh watever gets on to the science!!! sooooooooo first things first I want to apologize for an error in my pea blog, it doesnt matter if you choose the top dot or the bottom dot in the pea breeder thing, i thought it did so i was telling you which i chose but i found out in class it doesnt matter. ^ ^ anywhoo...i believe we did punnet squares and what not this fine week, soooo i'll start with the glorious square. weeeeee. SO its a lidl like lattice in a way (math people???) it is a square set up like when you draw a window on cruddy picture of a house: and then u list one chromosome pair (chromosome??? i think...) on top (like so ^) and then on the side. then you just match up the letter and put them in the square, like plotting points on a coordinate graph. eh-you get the point...
sooooo we did a real thrilling punnet square activity, wooooooo. we traced a traced a trait througth 3 generations of our fam and ill show you mine! :D yippee. uuuum mine was kinda screwy i think just so you know cuz of how my family is, as in i couldnt do one that showed me and my sister cuz we have diferent fathers, and i couldnt trace back my dads side of the family bcuz ive never met them, and obiously I couldnt just do my stepdads side of the fam cuz were not blood realated, so i did me, my moms parents, then my cousins on my moms side for the gemerations. wow you really didnt need the whole explaination did you??? (you: no Kelsey u stink!!! D:< ) im sorry! anyway, here are my results. i traced height and said tall was the dominant trait bcuz they are more tall people in the fam.

dad: TT mom: Tt = TT TT Tt Tt orange=me

pop: TT gram: tt = tT TT tT TT purple=mom red=uncle rich blue=aunt beth

uncle rich: tT aunt michelle: tt = tT tT tT tt pink=cuzin brad orange= cuzin jess

so i had to make e few assumptions bout homozygous and heterozygous to make it work but there you go. i really hope that made sense to you guys! they way i set it up is kinda confuzzling nad it will be even worse if stupid blogger goes and disorts it!!! D:< style="color: rgb(255, 153, 0);">QUESTION ONE!!! RAWR!!! for each genotype (vocab!) below indicate wether it is a homozygous (Ho) or heterozygous (he)

TT ho Bb He DD ho Ff he tt ho dd ho Dd he ff ho Tt he bb ho BB ho FF ho

*genotype- genetic code
*phenotype- physical appearance

which genotypes would be considered purebred? Homozygous ones because they have all the same genes

which would be considered hybrids? the heterozygous ones bcuz they have a mix of genes, some are just hidden.

Question 2!!! Determine teh phenotype using the info provided about spongebob

Yellow body color is dominant to blue

YY yellow Yy yellow yy blue

Square shape is dominant to round
SS square Ss square ss round

3!!!!! For each phenotype, give the genotypes that are possible for Patrick.

A tall (T) head is Dominant to short (t)

Tall= TT Tt Short= tt

Pink body color (P) is dominant to yellow (p)

PInk= PP Pp yellow= pp

4! Spongebob Squarepants recently met SpongeSusie Roundpants at a dance. Spongbob is heterozygous for his square shape but spongesusie is round. create a punnet square to show the possibilites if they had kids.

(So this means that she is homozygous.) i cant do the punnet square but ill tell you what i got.

A. List the possible genotypes and phenotypes for their children.

sS sS ss ss square, round.

B. What are the chances of a kid w/ a square shape?

2 out of 4 or 50%

C what are the chances of a kid with a round shape?
2 out of 4 or 50%

Patrick met patti @ the dance. both are heterozygous for their pink color, which is dominant over yellow. (im skipping the punnet square thing)

A. list possible genotypes and phenotypes for their children

PP Pp Pp pp pink yellow

B. what are the chances of a pink kid?

3 out of 4 or 75%

C. what are the chances of a yellow kid?

1 out of 4 or 25%

6. everyone in squidwards family has blue skin which is the dominant trait. His fam brags that they are purebred. He recently married a nice girl who has green skin which is the recessive trait. (skipping punnet square)

A. list possible genotypes and phenotypes for their kids.

bB bB bB bB green blue

B. what are the chances for a blue kid? 100%

C. What are the chances of a green kid? 0%

D. would squidwards kids still be considered purebred? explain!

no, because they would heterozygous, so there would still be a green gene in them, it just wouldnt show.

7. Assume that one of squidwards sons who is heterozygoud for his light blue color married a grl who was also heterozygous.

A. list possible genotypes and phenotypes for their children

bB bb BB Bb green blue

What are the chances of a kid w/ blue skin?

75%

what are the chances of a kid with green skin?

25%

Last question!!! this is hard to do without showing you the punnett square but the possible geno and phenotypes for their children are TT TT Tt Tt and they could only be tall so the hospital did make a mistake bcuz all the genotypes have @ least one dominant gene in them and tall eyeballs r dominant.

THE END!!! soooooooooooo that would be all. i have quite a bit of social studies to do so ive go to go!!!! hughughug!

bi bi!!!
