What type of mutation is likely to cause the most dramatic phenotypic change? A) Single nucleotide change that affects the third position in a codon
B) Single nucleotide insertion that changes codon groupings
C) Mutation that causes a new amino acid with similar chemical properties
D) Base pair substitution that codes for the same amino acid as original

The structure that houses the cells genetic information.

What type of cell division is used to replace old cell?

This problem has been solved! see the answeryou are investigating two traits in fruit flies controlled by one gene each. the b gene controls for body color (black or brown), while the r gene controls for body sculpture (rugose or smooth). after crossing rugose black flies with smooth brown flies, you obtain an f1 generation of 100% smooth black flies. what are the dominant alleles? (1 pt)what are the genotypes of the two parent flies to perform a dihybrid test cross? (1 pt)after running a dihybrid test cross, you find 1000 offspring with the following phenotypes: , rugose406black, smooth86brown, rugose94brown, smooth4141000fill in the expected column with the expected number of offspring in each class of phenotypes. (1 pt)what phenotype classes represent the recombinant offspring? (1 pt each)calculate the relative genetic distance between the body color gene and the body sculpting gene (show your work). (1 pt).
