Coupling vs Repulsion? The following testcross Aa Bb x aa bb produces 10 Aa Bb 40 Aa bb 40 aa Bb 10 aa bb Were the A and B alleles in the Aa Bb parent in coupling or repulsion and why?
12. Imagine a cross between AaBb x aabb produces progeny in the following proportions: | AaBb 31 aabb | 33. Aabb | 12 aaBb] 13 Based on this information, are genes A and B linked, or do they assort independently (Chi-square test)? IF linked, what is the genetic distance between A and B? Are gene A and B in coupling (cis) or repulsion (trans) conformation in the AaBb parent? How can you tell?
please help with these 3 questions. thank you! Name: A cross between individuals with genotypes AaBb x aabh produces the following offspring. Genotype Number of offspring AaBb Aabb aaBb aabb a. Do the evidence suggest that the a and b loci are linked? Explain your answer. b. What is the map distance between a and b? (Show your work.) c. Are the A and B loci in coupling or repulsion in the heterozygous parent? 4. You perform a testcross between...
A cross is set up: Aa Bbce X AA Bb Cc. What percentage of progeny will be heterozygous at every locus?
The following two genotypes are crossed: Aa Bb Cc dd Ee x Aa bb Cc Dd Ee. What will be the proportions of the following genotypes among the progeny of this cross? a.AaBbCcddEe b.AAbbCCddEE
3. A cross Aa Bb cc x aa Bb Cc was performed. Assuming genes A, B and C are independently assorted, how many phenotypes and their ratios can you predict? What is the probability of the Fl progeny phenotypically resembling either of the parents?
Please answer both Consider the following cross: Aa Bb Cc Dd x Aa bb Cc Dd. Assuming complete dominance and independent assortment, determine what proportion of the progeny will be homozygous dominant for all three genes? O 1/128 O 27/128 00 O 1/64 O 1/256 Which of the following statements is true? The observed frequency of recombination of two genes that are far apart from each other has a maximum value of 100% All of the traits that Mendel studied...
2. Consider the cross Aa Bb Cc Dd X aa Bb cc dd. All of the genes are on mes. What proportion of progeny will phenotypically resemble the second parent (i.e. the parent listed second in the cross)? Show each individual cross AS OUTLINED IN CLASS. Punnett squares are NOT allowed. Also, show the final calculation to get your answer. In other words, show all of your work.

In a cross between individuals with the following genotypes for 5 hypothetical genes: AaBbCCDdee x aaBBccDdEe; what is the probability that that one of the progeny would have a dominant phenotype (assume classical dominant/recessive pattern of inheritance for all 5 genes.? 1/16 3/16 1/32 3/32
по пре сосе. 1. A cross is made between two pea plants with the genotypes given below. ASSUME INDEPENDENT ASSORTMENT of all four genes. (2 points) Aa Bb Dd ee X Aa Bb dd EE a) What is the probability of obtaining a plant that is heterozygous for all four genes? b) What is the probability of obtaining a plant with the dominant phenotype for all four genes.
