There are two alleles for the arr gene, A and a. There are also two alleles for bee gene, B and b. The two genes are on a chromosome that is 1.5 micrometers in length, but it has yet to be determined if the two genes are linked. Below is data from a study to determine if the genes are linked, and if so, how far apart the genes are on the chromosome. An organism that is heterozygous for both...

Group of answer choices (This question allows me to answer for more than one answer choice but I'm not sure if there is really more than one) A) 0.2 B) 0.48 C) 0.8 D) 0.96

An individual has two different alleles of a particular gene. What’s true of the two alleles? A. They’re present on different chromosomes of a homological pair B. They code for slightly different forms of the same protein C. They’re separated from each other, into different daughter cells, in meiosis D. A and B are correct E. A, B, and C are correct

Which statement explains why the recombination frequency between two genes is always less than 50%? Recombination cannot be more than 50% because chromosomes are only 50 map units in length. The genotype of the F, gametes will always be 50% parental gametes and 50% recombinant gametes. Genes with a recombination frequency near 50% are unlinked and have an equal likelihood of being inherited together or separately. F1 gametes always have 50% of their alleles from each parental...

Different genes have been identified as causative for inherited forms of deafness. Because inherited deafness is a relatively rare characteristic in the population, individuals who are homozygous recessive for one gene that causes deafness are typically homozygous for functional alleles at other loci controlling the hearing phenotype. Knowing this, suppose a deaf man is homozygous for a recessive deafness allele on chromosome 17. He marries a deaf woman who is homozygous for a different recessive deafness allele on chromosome 3....

If alleles of different genes always maintain their parental association rather than assorting independently into offspring,...
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.

Q5. Closer examination of the two alleles of the human CDC25B gene reveals no changes in nucleotide sequence in the transcriptional unit. This observation indicates that the difference in nucleotide sequence between the two alleles must not occur within the transcriptional unit. Provide two possibilities where nucleotide changes could occur on the chromosome in the “_” allele that prevents production of CDC25B mRNA and explain why. (4 marks)
