F1 offspring obtained by monohybrid cross of AA and AA will be Aa.
The F1 generation consists of the offspring of a cross between two parents; the F2 generation consists of the offspring of a cross between two individuals in the same F1 generation.
P represents the parental generation in a genetic cross. F1 represents the offspring of the P generation.
It's a species of fish. A F1 is a cross between a Crucian Carp and a Common Carp.
The first generation of offspring from the cross of two parents is called the F1 generation.
The recessive trait phenotype disappears in a one-trait test cross in the F1 generation. This phenotype can reappear in the F2 generation.
The first generation cross, known as F1 (filial 1), for homozygous (purebred) parents will be heterozygous - have one allele of each of their parents' traits. For example, the cross BB X bb would result in an F1 genotype of Bb.
The expected phenotype ratio of seed color in the offspring of an F1 x F1 cross is 3:1. This is because the F1 generation is heterozygous for the trait, resulting in a 3:1 ratio of dominant to recessive phenotypes in the offspring.
when observing the F1 generation of a monohybrid cross
F2 refers to the F2 generation in genetics. First you have the P1 generation, or the 1st parents to cross. Next, their offspring is called the F1 generation. When the F1 generation offspring cross, then the F2 generation appears.
