IS ANYONE WILLING TO HELP ME WITH SOMETHING!!!!!!!!!!! PLEASE!!!!!!!!!!!:(

OpenStudy (anonymous):

I can probably help you! What do you need help with? :)

OpenStudy (anonymous):

3.04 HEREDITY PATTERNS.

OpenStudy (anonymous):

Its a quiz...

OpenStudy (anonymous):

Okay. :)

OpenStudy (abhisar):

Is it from a test ?

OpenStudy (anonymous):

Its 10 questions.......

OpenStudy (anonymous):

No its not from a test....

OpenStudy (anonymous):

Well.. I'll help you on a few questions. Not all of them though. You have to at lease try to do your own work. :)

OpenStudy (abhisar):

Post your questions one by one.

OpenStudy (anonymous):

I did twice and its my last time thats why i asked for help..... :(

OpenStudy (abhisar):

kisstherains is correct, we will guide you to the answer but u'll have to put some effort too,

OpenStudy (anonymous):

This pedigree chart tracks the inheritance of a recessive trait that is not sex-linked. Based on the information in the chart, which of the following statements is true? Individual #8 must be heterozygous for the trait. Individual #10 must be heterozygous for the trait. Individual #13 must be homozygous dominant. Individual #3 must be homozygous dominant.

OpenStudy (anonymous):

I only need help with 4 i got the rest right.....

OpenStudy (anonymous):

I think it's the second one..but I'm not sure. @Abhisar am I right? :)

OpenStudy (abhisar):

Let's suppose second one is correct. Now let's see what happening. #10 is showing recessive character and recessive characters are only expressed in homozygous condition. So what do you think, is second option correct ?

OpenStudy (anonymous):

the third one???? :/

OpenStudy (abhisar):

#13 is showing a dominant character which can be a result of both hetero and homo conditions.

OpenStudy (abhisar):

Have a look on the first option.

OpenStudy (anonymous):

okay......

OpenStudy (anonymous):

My bad.....

OpenStudy (anonymous):

If a baby boy inherits a recessive allele from his mother, in which of the following circumstances would he most likely exhibit that recessive trait? The allele is X-linked. His mother’s father also exhibited the trait. The allele skips a generation. He inherited the dominant trait from his father.

OpenStudy (anonymous):

I think its either the third one or the last one......??? :/

OpenStudy (abhisar):

wt is the scnd option ?

OpenStudy (anonymous):

His mothers fathers also exhibited the trait......

OpenStudy (anonymous):

Males are XY and females are XX. If the baby is a boy, it means he inherited the Y from his dad. He could have got either of his Mom's two X chromosomes. It means that even if the allele on the X is recessive the baby boy will express it because the Y does not have any alleles on it, dominant or otherwise. :)

OpenStudy (anonymous):

So its the second one????

OpenStudy (abhisar):

That's correct ! So the ryt option should be ?

OpenStudy (abhisar):

opes. not d scnd oneN

OpenStudy (anonymous):

@Tootles143 Good guess! But it's not the second one. :(

OpenStudy (anonymous):

I said that because Abbisar asked so i figured that was the right i said it either one of the last two.....

OpenStudy (abhisar):

Oops..i said correct for kriss

OpenStudy (anonymous):

#CONFUSED.... :(

OpenStudy (anonymous):

Lol I am too. xD

OpenStudy (abhisar):

Re read what kriss explained and make one more guess. The explanation of kriss is correct.

OpenStudy (anonymous):

So it D.......?

OpenStudy (abhisar):

Nopes it's the first one. What do u think kriss ?

OpenStudy (anonymous):

I agree, it's the first one. :)

OpenStudy (anonymous):

I am never going to understand this.......!!!! :O

OpenStudy (anonymous):

Don't say that! You'll soon get it. aha it just takes time. :)

OpenStudy (anonymous):

okay....... :(

OpenStudy (anonymous):

A mouse’s tail gets cut off. If the mouse has babies later, how will this affect the length of the tails of its offspring? It depends on the length of the mate’s tail. It will not affect the length of the tails of any of the offspring. It will affect the length of the tails of all the offspring. It will affect the length of the tails of some of the offspring

OpenStudy (anonymous):

Which one do you think it is?

OpenStudy (anonymous):

The second one...... :/

OpenStudy (anonymous):

You're right! What happens to a mouse's tail after it is born, within reason, does not affect their genes, which means that it will not be passed on to the offspring of the mouse.

OpenStudy (anonymous):

YYYYYYYYYYYYYEEEEEEEEEEEESSSSSSSSSSSSSS!!!!!!!!!! :D LOL

OpenStudy (anonymous):

I told you! It just takes time. lol xD

OpenStudy (anonymous):

In a monohybrid cross, if the gene for tall (T) plants was incompletely dominant over the gene for short (t) plants, what would be the predicted result of crossing two intermediate (Tt) parent plants? (Hint: You may want to complete a Punnett square.) 25 percent tall, 50 percent intermediate, 25 percent short 50 percent tall, 25 percent intermediate, 25 percent short 100 percent intermediate 25 percent tall, 75 percent intermediate

OpenStudy (anonymous):

lol

OpenStudy (anonymous):

I think its the first..... ? ;/

OpenStudy (anonymous):

It is the first one. Good job! ^.^

OpenStudy (anonymous):

What are the genotypes of the parents in the monohybrid cross below if the following offspring genotypes are predicted? ? ? ? TT Tt ? Tt tt Tt and Tt TT and tt Tt and TT Tt and tt

OpenStudy (anonymous):

Is it the first one????

OpenStudy (anonymous):

Is there a picture or a graph for this question?

OpenStudy (anonymous):

Yeah.....

OpenStudy (anonymous):

Can you please post it so I can see it? :)

OpenStudy (anonymous):

I cant it isnt a picture or anything......... :(

OpenStudy (anonymous):

Are you still going to help me......?

OpenStudy (anonymous):

In fruit flies, the gene for red eyes (R) is dominant and the gene for sepia eyes (r) is recessive. If two red-eyed heterozygous flies (Rr) mate together, what are the possible genotypes of their offspring? (Hint: You many want to complete a Punnett square.) RR and Rr Rr only RR and rr RR, Rr, and rr

OpenStudy (abhisar):

Very impressive work @kisstherains ! Pat your back..keep up the good work :)

OpenStudy (anonymous):

@kisstherains ???

OpenStudy (anonymous):

Yes, sorry. I was afk. :) Thanks @Abhisar

OpenStudy (anonymous):

I don't really understand that question, that's why I asked you if there was a picture or graph. lol

OpenStudy (anonymous):

thats alright/...

OpenStudy (anonymous):

I believe it's the last one. :)

OpenStudy (anonymous):

okay thanks..... may you help me with a few more....

OpenStudy (anonymous):

I would love to help you! Just make a new post. :)

OpenStudy (anonymous):

f a corn plant has a genotype Sstt, what are the possible genetic combinations that could be present in a single grain of pollen produced by the plant? Ss, tt, St, st Ss, tt, St, ST St, st St, sT, st
