In a F2 generation of 80 individuals, you would expect about 3 individuals to show a trait that follows a typical Mendelian inheritance pattern with a 3:1 ratio in the offspring generation. This is based on the expected ratio of 1:2:1 for a heterozygous cross.
In the F2 generation, the offspring that produced green peas likely had the genotype "tt," where "t" represents the allele for green peas and "T" represents the allele for yellow peas. Since one out of four offspring produced green peas, this follows a typical Mendelian ratio of 1:2:1 for a monohybrid cross. The parental generation would have been heterozygous (Tt), allowing for the segregation of alleles.
Asexual reproduction uses only 1 parent and is usually only done by bacteria. Also the offspring is an exact copy of the parent. Then sexual reproduction requires 2 parents and the offspring is a mix of the 2 parents' genes.
In genetics, F1 refers to the first generation of offspring resulting from a cross between two parental organisms. This generation is typically used for studying inheritance patterns and determining genetic traits passed down from the parents.
Offspring that posses two different forms of the same gene. These are called alleles.
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.
In the P generation, one parent is homozygous dominant and the other parent is homozygous recessive. In the F1 generation, the product of a cross between the P generation, the offspring are all heterozygous. In the F2 generation, the product of a cross between the F1 generation, the expected result is 1/4 homozygous dominant, 1/2 heterozygous, and 1/4 homozygous recessive.
An F1 x F1 cross would be a cross between heterozygous (Tt) parents. The offspring would be 1/4 TT, 1/2 Tt, and 1/4 tt. This would mean that 3/4 of the offspring would be tall, and 1/4 would be short.These offspring would be the F2 generation.

depends how it self fertilises. If the gametes are produced with random genes in them the offspring could have recessive charateristics not displayed on the parent. However it could only have charateristics that were present in the parents genotype to begin with. If the offspring has the same genotype as tha parent then it would be the exact same.
