In Parakeets, Yellow (B) is dominant to Blue (b), long beaks (S) are dominant to short beaks (s)
In Parakeets, Yellow (B) is dominant to Blue (b), long beaks (S) are dominant to short beaks (s), and being quiet (N) is dominant to being noisy (n). You perform a test cross of a trihybrid parakeet (BbSsNn) and a triple recessive parakeet. The following results are obtained Phenotype:Genotypeof progenyBlue, short, quiet13Yellow, long. noisy13Yellow, long, quiet436Blue, short, noisy450Yellow, short, quiet165Blue, long, noisy162Blue, long, quiet82Yellow, short, noisy79Total1400A.

You are working with a hypothetical fly and have found color and wing mutants. Preliminary work indicates that the mutant traits are recessive and the associated genes are not sex-linked, but beyond that you have no information. You first look at 2 genes, each with two alleles: "Borb" for body color and "Wor w" for wing surface. The red body phenotype is dominant to the yellow body...

5. You started working in a Drospohila lab. You are studying two different autosomal traits, body color and antennae length. Gray body (B) is completely dominant to black body (b) and long antennae length (A) is completely dominant to short antennae length (a). You cross true-breeding gray bodied, long antennae files to true-breeding black bodied, short antennae. The F1 progeny all have gray bodies and long antennae. a. You perform a testcross to the F1 progeny produced from the parent...

In beetles, a gene coding for body color and a gene coding for bristle length are located on the same chromosome. Black (B) is dominant over grey body (b) and long bristles (s) are recessive to short bristles (S). A beetle that is heterozygous for black body and short bristles is mated with one that has a grey body and long bristles. What are the genotypes of the parents? ____________ ____________ Assume that the B allele is linked with the...

Question 25 Not yet answered Points out of 2.50 Klinefelter syndrome XXY is the set of symptoms that result from two or more X chromosomes in males. The primary features are infertility and small poorly functioning testicles. However, very often, symptoms may be subtle and many people do not realize they are affected. Which of the following statements might explain why symptoms are subtle in many Flag question cases? Select one: a. In males, the important sex chromosome is the...

Drosophila genetics hw. Can someone help explain this
You are doing a genetics experiment with the fruit fly. In the "P" generation, you cross two true-breeding flies. The female parent is brown and wingless and the male parent is black with normal wings. All of the flies in the F1 generation are brown and have normal wings. Indicate the alleles associated with dominant phenotypes by uppercase letters and alleles associated with recessive phenotypes by lowercase letters. Assume the genes are...

A new gene is being investigated in fruit flies. The recessive allele of this gene (b) causes the wings to develop a blue color, while the dominant allele (b) permits wild-type colorless wings to develop. Preliminary studies indicate that this new gene is located on the X-chromosome. You decided to perform a two-point testcross to determine its position relative to the well-established garnet eyes gene (g). You cross a female heterozygous for both genes with a testcross male fly, and...

You infect E. coli with two strains of T4 bacteriophage with genotypes +B+ and A+C. You collect and analyze 1000 plaques, obtaining the following results: ABC = 31 +++ = 36 AB+ = 4 A+C = 410 A++ = 50 +BC = 46 +B+ = 421 ++C = 2 Draw a map with distances for the three genes. Which gene is in the middle? Calculate the interference.
