Why is possible for two very closely linked genes to be transduced together in the same donor phage, but it is not possible for two genes that are far apart to be transduced together?

1.) Explain why linkage measurements are more accurate for two genes that are close together than two genes that are farther apart. 2.) A female poodle with green eyes (recessive) and yellow spots on her tongue (recessive) was bred with a male poodle who was the wild-type phenotype but hybrid genotype for those same two traits. In a series of litters, this breeding pair gave birth to the following 85 puppies: 39 Normal eyes, normal tongue 36 Green eyes, yellow-spot...
Question: A bacterium with genotype A+B-C-was transduced by a particle carrying the linked genes A-B+C+, and A+B+C+ recombinants were selected. The reciprocal cross was also performed. The number of A+B+C+ recombinants was the same in both the first cross and the reciprocal cross. What information does this give you about the order of the three genes? (please explain in as much details)- these genes are assumed as any random genes
Explain why linkage measurements are more accurate for two genes that are close together than two genes that are farther apart. Why are genes more than 50cM away from each other considered “unlinked?” If two genes are 75cM away from each other, they are not genetically linked, so how do we even know that they are 75cM away from each other?

Question 20 3 pts recombination frequency Two linked genes that are close together usually have a than two linked genes that are further apart. Question 21 3 pts DNA polymerase Ill requires to build something before it can begin replicating. 3 pts Question 22 mutations in a gene always results in a new stop codon in the transcribed mRNA
A generalized transducing phage is used to transfer genes from a thr(+)bio(+)thi(+) donor strain of E. coli to a thr(-)bio(-)thi(-) recipient strain. When transductants selected on a medium containing thiamine and threonine are tested for growth on other media, many more colonies are found on media supplemented only with threonine than on media supplemented only with thiamine. No transductants survive on minimal media. What is the correct order for these three genes? *I have seen multiple different answers for this,...
You see a recombination frequency of 0.0313%), what does this indicate? That the genes are located close together on the same chromosome That the offspring has a large number of non-parental phenotypes That the genes are on different chromosomes That the genes are assorting independently That the genes are located on the same chromosome, but very far apart
A plant of genotype AB/ab- yes, the two genes are linked is testcrossed to an ab/ab plant. if the two genes are 10 map units apart, then what fraction of progeny will be AB/ab?
You see a recombination frequency of 50% between two genes. Which of the following possibilities can you exclude? That the genes are located close together on the same chromosome That the genes are on different chromosomes O That the genes are assorting independently That the genes are located on the same chromosome, but very far apart Meiosis contributes to genetic diversity by: o Reducing the number of chromosomes for karyogamy (fusion of nuclei) with another gamete O Recombining homologous chromosomes...
If alleles of different genes always maintain their parental association rather than assorting independently into offspring, this is because Options: a) Mendel's experiments were flawed. b) they are really alleles of a single gene. c) there was a meiotic error. d) they are very close together on the same chromosome. e) they are on the same chromosome but far apart.
