F1 And F2 Generation Punnett Square
You calculated the phenotypic probability for the trait you are interested in.
F1 and f2 generation punnett square. Based on the results it was confirmed that a ratio could be formulated according to the phenotype of the f2 generation that is 31. The cross between the true breeding p plants produces f1 heterozygotes that can be self fertilized. Punnett squares punnett squares are a useful tool for predicting what the offspring will look like when mating plants or animals. Now cross two of the offspring from the f1 generation to get the f2 generation.
You set up your punnett square. All of the f1 flies produced by this cross both males and females had red eyes. The cross between the true breeding p plants produces f1 heterozygotes that can be self fertilized. Next morgan crossed the red eyed f1 males with the red eyed f1 females to produce an f2 generation.
You performed the cross. Lets take a look at how punnet squares work using the yellow and green peas example from mendels garden experiments. You determined the phenotypes of the f1 generation. A punnett square shows the genotype s two individuals can produce when crossed.
The punnett square below shows morgans cross of the f1 males with the f1 females. The punnett square in the post lab questions document. Reginald crundall punnett a mathematician came up with these in 1905 long after mendels experiments. The self cross of the f1 generation can be analyzed with a punnett square to predict the genotypes of the f2 generation.
Given an inheritance pattern of dominant recessive the genotypic and phenotypic ratios can then be determined. Given an inheritance pattern of dominant recessive the genotypic and phenotypic ratios can then be determined. Download the pdf of f1 vs f2 generation. To draw a square write all possible allele combinations one parent can contribute to its gametes across the top of a box and all possible allele combinations from the other parent down the left side.
However these results will not be the same for every cross with the same parents. The self cross of the f1 generation can be analyzed with a punnett square to predict the genotypes of the f2 generation. This is the difference between f1 and f2 generation. Punnett squares show the statistical outcome or the predicted results of crosses.
