. In rye grass, seed color is a polygenic trait (additive model). If true-breeding red and white varieties are crossed, the F1 are intermediate in color. If the F1 are self-fertilized, about 1 in 64 have white seeds. If the F1 are testcrossed, how many different genotypic categories will be produced?

The GTP binding domain of elongation factor Tu (EF-Tu) and elongation factor 1α
The GTP binding domain of elongation factor Tu (EF-Tu) and elongation factor 1α (EF-1 α) contains an eight amino acids conserved region, with the sequence FIKNMITG (using the one letter code). Here you are designing only one of the two primers required for PCR.
a. If you were using this region to design a primer to amplify by PCR the sense strand of EF-Tu/EF-1
In green turtles, an odd number of plates on there shell is dominant over an even number of plates. On the same chromosome is a gene for ear spot color with red being dominant over orange. On this same chromosome is the gene for strip color on the body with yellow being incompletely dominant with blue strips. These turtles were crossed in a breeding experiments and the following dat
DNA Synthesis: heated and cooled, fregments & total DNA. hybridized? Help!
1- During DNA synthesis, small fragments of DNA are formed. They were collected and combined with total DNA. The mixture was heated and cooled down. What would you expect to happen? a. The small fragments would hybridize together b. The small fragments would not hybridize to native DNA c. The small fragments would hybridize to the leading strand; the
You decide to cross the reciprocal translocation strain to a pure (black, sepia)
You decide to cross the reciprocal translocation strain to a pure (black, sepia) line to generate female F1 flies that are both translocation heterozygotes and BbSs dihybrids.
You then backcross these F1 females to males from the pure (black, sepia) line. This diagram shows synapsis in the F1 females. (In the diagram, NII = normal chromosome II; TII = translocated chromos

Calculate the number of mismatches that could occur in one human cell during one round of replication. Assume the size of the human genome is 3.2 billion base pairs. Assume the error rate is 1 mismatch per 10^10 bp. Express your answer using two significant figures.
Calculate the number of mismatches that could occur in one human cell during one
Calculate the number of mismatches that could occur in one human cell during one round of replication in the absence of mismatch repair. Assume that mismatch repair decreases the number of mutations by a factor of 1000. Express your answer using two significant figures.

A given enzyme consists of two subunits (a dimer), which are specified by a single gene locus.
i.If a = normal subunit and a’ = mutated subunit, what subunit combinations might be found in a heterozygote, assuming random association between these subunits?
ii.If the mutation resulted in a net change in the charge of the molecule, how many bands would be detecta
I am having trouble with this quantification method. I am a CS major working in a developmental biology lab so I do apologize before hand if this question is dumb.
The MAK2 model for qPCR is: "Dn = (Dn-1) + (k)ln(1+((Dn-1)/k))", "Dn" is the value at cycle "n". "D0" and "k" are the only two adjustable parameters that deter

Hello I need to help with some biology genetics and prognosis, can you answer this question for me with a detail explanation, and also could you explain how different diseases, i.e. AR, AD, GD, and GR, are answered in similar questions. Regarding the question. Estimate the probability of affected children in IV generation autosomonal recessive disease with the frequency of 1 si
Visualizing exons and their respective trancripts and protein domains.
I am building a script that takes exons from a particular gene and then plots them by their base pair coordinates on a 2D graph. Using data from Ensembl, I can match each exon to its respective transcript and protein domain.
I use data from Ensemble to match each domain to the gene base pairs responsible for its formation; I can then plot the protein domains above their r
Where does the cut take place in palindrome sequence
In the case of restriction enzymes, I know that it chooses Palindromes, but where does the exact cut take place? Is it always between A and T base pairs or Can it occur between any base pairs in a palindrome sequence.
Identify the phenotypes and genotypes of all the people shown in this pedigree.
Complete Practice Problem 20 on page 615 in the textbook. Identify the phenotypes and genotypes of all the people shown in this pedigree. Rolling the tongue (R) is dominant over inability to roll the tongue as it remains flat (r).
Hint: What kind of inheritance is this? How do you assign symbols? See (sr) Pedigree Analysis. Did you assign all non-shaded individuals
Identify the most likely mode of inheritance found in this pedigree
I think that the most likely mode would be autosomal dominance with incomplete penetrance because it did skip one generation. Any help would be greatly appreciated. Let me know what you think it is and please also write why you think it is that. Thanks!

I am in serious need of correction or confirmation please! I am going to throw out some random facts and please let me know if I am accurate or not. Thanks for helping!
F1 hybrid can only be created by using two separate parents from inbred lines or P1. F1 are uniform, showing a new phenotype without variation. Not even once in a while will you see a second phenotype show
The likelihood of having identical children (who are not twins)
