Why didint Morgan find white eyed female d melanogaster in the f2 generation when he crossed white eyed males with red eyed females?
Because when he went home, he imediatly had sex with his seven year old sister. He realized that he was a nothing, turned to crack and minecraft, and killed himself before his eleventh birthday.
What is F3B labradoodle?
An F1 Labradoodle = Poodle crossed with a Labrador Retriever.F2 = F1 Labradoodle crossed with F1 LabradoodleF3 = F2 Labradoodle crossed with F2 Labradoodle etcWhen mixing generations, you add one to the lower generation parent, ie F4 cross F1 = F2, or F3 cross F2 = F3 etcF1B, F2B, F3B etc just means a backcross to one of the parent breeds, usually the poodle, thus F3B = F3 Labradoodle cross Poodle
A blue feathered bird is crossed with a white feathered bird All the F1 generation are blue What would be the genotype for the F2 generation?
The F2 generation would have a mix of genotypes for feather color, depending on the genetic makeup of the F1 birds. Assuming the blue feathered bird is homozygous dominant (BB) and the white feathered bird is homozygous recessive (bb), the F1 generation would be heterozygous (Bb). In the F2 generation, there would be a phenotypic ratio of 3:1 for blue to white feathers and a genotypic ratio of 1:2:1 for BB:Bb:bb.
If tall peas are crossed with dwarf peas what percent of the peas will be tall in the first generation?
In the first generation of crossing tall peas with dwarf peas, all the offspring will be tall. This is because the tall trait is dominant over the dwarf trait. Each offspring will inherit one tall allele from the tall parent, resulting in all tall offspring.
When thomas hunt Morgan crossed his red-eye f1 generation flies with each other the f2 generation included both red and white eyed flies why were all the white-eyed flies male?
The white eyed flies that resulted from the crossing of the red-eye flies were all male as the gene involved was on the X chromosome. The X chromosome is the male chromosome.
Explain why morgan did not find white-eyed female d melanogaster in the f2 generation when he crossed white-eyed males with red-eyed females?
Morgan did not find white-eyed female Drosophila melanogaster in the F2 generation because the gene for eye color is located on the X chromosome. Since the white eye trait is recessive and carried on the X chromosome, the F1 generation produced all red-eyed females (carrying one normal X allele from the red-eyed mother) and white-eyed males (carrying the recessive white allele inherited from the white-eyed father). Therefore, there were no white-eyed females in the F2 generation because they would need to inherit a white allele from both parents, which was not possible in this particular cross.
What generation are the parental organisms that are crossed called?
The parental organisms that are crossed are typically of two different generations or lines: the P1 generation, which are the original parents, and the F1 generation, which are the offspring resulting from their cross.

Why is your sun a 2nd generation star?
because he crossed the road
How did make the f1 generation for his experiments?
he crossed two pure lines
How did mendel the F1 generation for his experiments?
he crossed two pure lines
Formed when two different purebreds are crossed?
A hybrid.
The first two individuals that are crossed in a breeding experiment are call the?
P generation
When parent plants are crossed how do scientists refer to the first generation of offspring?
F1
What are the first two individuals that are crossed in a breeding experiment?
the P (parental) Generation
How did Mendel make the F1 generation for his experiment?
he crossed two pure lines
How do you explain Mendel's mono hybrid cross 1?
Mendel crossed a pure-breeding round-seeded variety with a pure-breeding wrinkled-seeded one. All the peas produced in the second or hybrid generation were round.
