What is the phenotypic ratio of the?
Asuming that the F1 generation is heterozygous for a single trait and that the F2 cross is of 2 F1 offspring. Ex. Aa X Aa the phenotypic ratio is 3:1 dominant to recessive. The genotypic ratio is 1:2:1 AA:Aa:aa.
What is the phenotypic of the F2 generation?
Asuming that the F1 generation is heterozygous for a single trait and that the F2 cross is of 2 F1 offspring. Ex. Aa X Aa the phenotypic ratio is 3:1 dominant to recessive. The genotypic ratio is 1:2:1 AA:Aa:aa.
Which cross would produce the least phenotypic variation?
There are two choices that produce the least phenotypic variation. AA times aa produces only Aa offspring. AA times Aa produces and AA and Aa offspring.
What is the phenotypic ratio of a monohybrid cross?
In a monohybrid cross with one parent homozygous dominant and the other homozygous recessive The phenotype of the F1 offspring will be 100% that of the parent with the dominant allele. A cross of two of the F1 offspring will be 75% phenotypically like the dominant allele and 25% will be hommozygous recessive or 3 to 1
What is the genotypic ratio of the offspring from a cross of AAA x AAA?
The genotypic ratio of a cross of Aa and Aa is: one AA, one aa, and two Aa. Or 1:2:1
What is the phenotype ratio of a cross between a heterozygous male and female?
The phenotypic ratio is a 3:1 ratio.
The phenotypic ratio resulting from a dihybrid cross showing independent assortment is expected to be what?
The phenotypic ratio resulting from a dihybrid cross showing independent assortment is expected to be 9:3:3:1. This ratio is obtained when two heterozygous individuals are crossed for two traits that are independently inherited. The ratio represents the different combinations of phenotypes that can arise from the cross.
Why does the expected genotypic ratio often differ from the expected phenotypic ratio from monohybrid cross?
Because in heterozygotes, both alleles are transcribed and translated.
A 1 to 2 to 1 phenotypic ratio in the F2 generation of a monohybrid cross is a sign o?
incomplete dominance
What is the phenotypic ratio of the F-2 generation of the monohybrid cross?
1 Red : 2 Pink : 1 White
If you performed the Drosophila cross LL x ll what phenotypic ratio would you expect among the offspring?
3:1
What is the expected phenotype ratio of seed color of the offspring of an F1 x F1 cross?
If the parents were AA and AA for example then the phenotype ratio will be 1 A (the dominant allele). The genotype will be 1Aa.
