yy is the homozygous dominant genotype (2 y alleles). The phenotype of this genotype is green seed color. … So, the F1 generation all have identical genotypes, heterozygous at the seed color gene, and their phenotypes are yellow seeds.
What is the phenotype in the F1 generation?
As expected from the 1st law, the F1 generation shows a uniform round yellow phenotype, since one dominant and one recessive allele was inherited from the parents.
What will be the genotype of F1 generation?
All of the F1 generation plants will have the genotype of Ss (heterozygous), and all will be spherical seeded.
What is the genotype of the F1 generation quizlet?
In the cross-pollination between a true-breeding yellow pod plant (gg) and a true-breeding green pod plant (GG), where green pod color is dominant, the resulting offspring (F1 generation) will be all green (Gg, Gg, Gg, Gg). The genotype of the F1 plants is (Gg).
How do you find the F1 generation?
The initial generation is given the letter “P” for parental generation. The first set of offspring from these parents is then known as the F1 generation. The F1 generation can reproduce to create the F2 generation, and so forth.
What means phenotype?
A phenotype is an individual’s observable traits, such as height, eye color, and blood type. The genetic contribution to the phenotype is called the genotype. Some traits are largely determined by the genotype, while other traits are largely determined by environmental factors.
Under what conditions does one expect a 1 1 1 1 genotypic ratio?
Under what conditions does one expect a 1:1:1:1 ratio? This occurs in a cross involving doubly heterozygous individuals crossed to fully recessive individuals. The genes involved assort independently of each other.
Which two genotypes in an individual would be expressed as the same phenotype in a diploid organism?
Which two genotypes in an individual would be expressed as the same phenotype in a diploid organism? homozygous dominant and heterozygous (Both of these genotypes would express the dominant phenotype.
