(Assume complete dominance)., The 3:1 phenotypic ratio observed among progeny of an F1 X F1 cross requires random union of gametes., Of the methods listed below, which would be the best way to determine which of two alleles of ...

Solved 1. The wild-type (normal) fruit fly, | Chegg.com

1. The wild-type (normal) fruit fly, Drosophilia melanogaster, has straight wings and long bristles.Mutant strains have been isolated that have either curled wings or short bristles. The genes representing these two mutant traits are located on separate chromosomes.

What is the phenotype of vestigial wings?

The phenotype of vestigial (short) wings (vg) in Drosophila melanogaster is caused by a recessive mutant gene that independently assorts with a recessive gene for hairy (h) body. Assume that a cross is made between a fly with normal wings and a hairy body and a fly with vestigial wings and normal body hair. The wild-type F1 flies were crossed among each other to produce 1024 offspring.

What did Mendel postulate about hereditary traits?

By noting that traits passed unaltered from parental to subsequent generations, Mendel not only postulated the unit or particulate nature of hereditary elements , but also described their behavior.

What mutants were used to plated E. coli B?

Using mutants 2 and 3, following mixed infection on E. coli B, progeny viruses were plated in a series of dilutions on both E. coli B and K12 with the following results.

Why is there a higher likelihood that the null hypothesis will be rejected?

As the χ 2 values increase(s), there is a higher likelihood that the null hypothesis will be rejected because increased values are more likely to be associated with a p-value that is less than 0.05.

What type of fly has long wings?

The wild-type (normal) fruit fly, Drosophila melanogaster, has straight wings and long bristles. Mutant strains have been isolated that have either curled wings or short bristles. The genes representing these two mutant traits are located on separate chromosomes. Carefully examine the data from the five crosses shown below (running across both columns).

What stage of embryogenesis is tail-like?

Between stages 14 and 22 of human embryogenesis, one can actually observe a tail-like structure that is later absorbed (except when it isn't... which can happen ). Advertisement. This feature of embryological development was one of the mainstays of Ernst Haeckel's theory of recapitulation.

What is the first line of defense against pathogens?

Tonsils are purported to be the body's first line of defense against inhaled or ingested pathogens, but they, like the appendix, have a nasty habit of taking up arms and joining the opposing force in the ongoing war-of-infection waged against your body.

What is the phenotype of vestigial wings?

Assume that a cross is made between a fly with normal wings and a hairy body and a fly with vestigial wings and normal body hair.
