In a fruit fly experiment, grey body, normal winged (homozygous dominant) fruit flies were mated with black body, short winged (

homozygous recessive) fruit flies. The F1 dihybrid females were then used in a test cross. If the genes are always linked and no crossing over occurs, what would be the predicted ratio in the F2 generation?
A. 9:3:3:3
B. 1:1:1:1
C. 3:1

Answer:

In a fruit fly experiment, grey body, normal winged (homozygous dominant) fruit flies were mated with black body, short winged (homozygous recessive) fruit flies. The F1 dihybrid females were then used in a test cross. If the genes are always linked and no crossing over occurs, what would be the predicted ratio in the F2 generation?

GG x bb = Gb, Gb, Gb and Gb  F1 generation

grey body heterozygous offspring 4:0

Gb x Gb= GG, Gb, Gb, and bb F2 generation

3:1 three grey body fly and one black body fly

A population of white-tailed deer inhabits a certain patch of forest in michigan. Which group of alleles can be considered the g
emmainna [20.7K]

Answer:

the dominant alleles of white-tailed deer in this population only!

Explanation:A group of individuals of the same species that interbreed with each other is known as a population. The study of change in genetics is called population genetics which includes genes and alleles.  

Complete set of genes and their alleles that are present in a population is called gene pool. Gene pool includes both dominant and recessive alleles of every gene present in a population that can be transmitted in the next generation.

Population with high genetic pool has high diversity which increases the fitness of a population. As gene pool include all the genes and its allele in a population, therefore, the correct answer is all alleles of the white-tailed deer in this population only.
