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 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
How do the experimental ratio compare with the expected ratio?
The two are very different....
When flies having a gray body and normal wings were crossed with flies having a black body and vestigial wings the F2 generation showed a phenotypic ratio of 3 1 and not 9 3 3 1?
Your answer is A
How can you be sure of getting the expected 50 to 50 ratio from flipping a coin?
You can't be sure to get the 50/50 ratio of heads and tails. Each time will be a trial & error.
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.
Why does the expected genotypic ratio often differ from the expected genotypic ratio resulting from a monohybrid cross?
becouse you touch yourself at night.
If both parents were Dd then what would the phenotypic ratio be?
Phenotypic ratio: 3 D, 1d [3 dominant, 1 recessive] Genotypic ratio: 1DD, 2Dd, 1dd
A homozygous dominant brown mouse is crossed with a heterozygous brown mouse (White is the recessive color)?
A pretty bow
What is the expected genotype ratio for a one-factor cross of two hybrid organisms?
The phenotypic ratio of 2 hybrids would be 3:1 while the genotypic would be 1:2:1. ChaCha on!
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.
What is the importance of a 9331 ratio in a monohybrid cross?
The phenotypic ratio expected from a monohybrid cross between heterozygotes is 3:1 (assuming complete dominance), with the genotypic ratio being 1:2:1. So, using tall = T, short = t and R = red, r = white as an example. A monohybrid cross of Tt X Tt would be expected to produce 3 tall plants and 1 short plant (phenotypic ratio 3:1), which would be 1 TT, 2 Tt and 1 tt (genotypic ratio 1:2:1). A dihybrid cross of heterozygotes is expected to produce a phenotypic ratio of 9:3:3:1. So the cross of TtRr X TtRr would be epected to have: 9 tall red, 3 tall white, 3 short red and 1 short white (phenotypic ratio) This is because each parent has 4 possible combinations of gametes (TR, Tr, tR and tr). There are therefore 16 combinations of gametes, providing a 9:3:3:1 phenotypic ratio. Both of these are probably best visualised using a punnett square (see link below).
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.
What a ratio?
A genotypic -ratio reflects the genetic configuration of an individual in the population. Several genotypes are possible in a phenotype and the ratio in which the genotypes segregate in a given phenotype is known as its genotypic ratio.
Color blindness is an X-linked recessive trait A color-blind man has a daughter with normal color vision She mates with a male who has normal color vision What is the expected phenotypic ratio of t?
The phenotypic ratio will be 1:3.his son will be color blind.
What is the genotypic ratio for a tetrahybrid cross?
1:1:1:1:1:1:1:1 ratio is the expected outcome of a heterozygous (BbGgCc) and a homozygous recessive (bbggcc) cross.
