- you are a zoologist working with Tigers. Their dominant traits are Bright orange fur(B+), Long tails (L+), and sharp teeth (T+) . You perform the following testcross with an individual with recessive versions of all 3 of the traits. P: B+ L+ T+/B+ L+ T+ x B L T /B L T F1(all identical): B+ L+ T+/ B L T Test Cross Progeny 3435 B L T 3069 B+ L+ T+ 1115 B+ L T 1022 B L+ T+ 426 B L T+ 428 B+ L+ T 114 B L+ T 102 B+ L T+ Total progeny= 9711 question: What is the distance between B and L?

The F1 offspring are then bred to fruitflies of genotype aabb. The F2 offspring have the following genotypes: Aabb 14 flies AaBb 413 flies aabb 419 flies aaBb 15 flies a. Are genes A and B on the same chromosome? Yes No b. Show how you would calculate the genetic distance between genes A and B.arrow_forward
- The image shows a pair of homologous chromosomes from a single parent before gamete production. M1 and M2 are maternal chromosomes, while P1 and P2 are paternal chromosomes. Two traits are shown: D represents seed color (D – green, d – yellow), while F represents flower color (F – purple, f – white). These two traits follow the patterns of basic Mendelian genetics. During crossing-over between the M2 F allele and the P1 f allele, a mutation occurred and the portion of P1 did not reattach to the chromosome. Which of the following explains what would happen to the proportion of white flowers in a population resulting from this mutation? A - There would be an increase in the proportion of white flowers because the f allele is distributed to more gametes. B - There would be a decrease in the proportion of white flowers because the f allele is not distributed to as many gametes. C - There would be an increase in the proportion of white flowers because the f allele would not be masked by the…arrow_forwardPlease SHOW YOUR WROK DRAW IF YOU NEED TOO.arrow_forwardyou are a zoologist working with Tigers.
