please help will give medal and fan unless Im already ur fan

OpenStudy (winsteria):

Your question?

OpenStudy (anonymous):

sorry my computer was being weird

OpenStudy (winsteria):

it's okay :)

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 about individuals 3 and 4?

OpenStudy (anonymous):

there is a chart to hold on

OpenStudy (anonymous):

here it is

OpenStudy (winsteria):

Well what do you think it is?

OpenStudy (anonymous):

I think it is the first one At least one is heterozygous for the trait.

OpenStudy (winsteria):

Well they're both Phenotype Exhibited, but one is female and one is male. But I'm not the best at this type of Science, but I'd agree with your answer.

OpenStudy (anonymous):

ok thank you very much here is your medal

OpenStudy (winsteria):

Thanks I hope you get it right :)

OpenStudy (anonymous):

I hope so to

OpenStudy (anonymous):

thank you

OpenStudy (winsteria):

You're welcome!

OpenStudy (anonymous):

i'll let u know wat I get when I turn in my assignment

OpenStudy (winsteria):

Okay

OpenStudy (anonymous):

do u feel like answering or helping to answer another question

OpenStudy (winsteria):

I can try, like I said I'm not the best at this Science but I can try

OpenStudy (anonymous):

thank you do you know what a punnett square is

OpenStudy (winsteria):

The Punnett square is a diagram that is used to predict an outcome of a particular cross or breeding experiment. These tables give the correct probabilities for the genotype outcomes of independent crosses where the probability of inheriting copies of each parental allele is independent. The Punnett Square is a visual representation of Mendelian inheritance.

OpenStudy (anonymous):

wow yes exactly so that is basically what this question is just a little more ok here it is

OpenStudy (anonymous):

In pea plants, purple flowers (P) are dominant over white flowers (p) and tall stems (T) are dominant over short stems (t). Complete a dihybrid cross for parents with the genotypes: PpTT × ppTt and answer the following in complete sentences. Describe how you would set up a Punnett square for this cross. List the likelihood of each possible offspring genotype. List the likelihood of each possible offspring phenotype.

OpenStudy (anonymous):

ignore the ?????? in the diamonds

OpenStudy (winsteria):

Okay give me a min

OpenStudy (anonymous):

ok no problem

OpenStudy (winsteria):

I think, it is Tt n Pp

OpenStudy (winsteria):

List the various combinations in which the alleles can sort. For the first parent, each p allele can sort with each t allele, so the combinations which involve the P allele are P T1 and P T2 (where the T allele on one chromosome is denoted T1 and the T allele on the other is denoted T2). The combinations which involve the other p allele are p T1 and pT2. For the second parent, p1 denotes the p allele on one chromosome and p2 denotes the p allele on the second. The possible combinations are p1 T, p1 t, p2 T and p2 t. You line these up on the sides of the grid, do the cross, and look at the frequency at which the different genotypes (and phenotypes) arise to analyze the cross.

OpenStudy (winsteria):

This should help as well :) https://answers.yahoo.com/question/index?qid=20120801104231AA2fpYB

OpenStudy (anonymous):

woow thank you very much

OpenStudy (anonymous):

if I could give u a medal I would but I can't do it twice do u know any other way

OpenStudy (anonymous):

that really helped thank you

OpenStudy (winsteria):

No I don't know any other way lol, only if you open up another thread, and you're welcome :)

OpenStudy (anonymous):

ok Ill do that
