The genotype of the F1 generation from a cross between TT and tt will be Tt (all offspring will be heterozygous).

The height of the F1 generation will be tall, as tall is the dominant trait.

The expected phenotypic ratio in a dihybrid cross is 9:3:3:1.

In a pedigree chart, a filled circle represents an affected female.

A test cross is performed by crossing an individual of unknown genotype with a homozygous recessive individual.

In a test cross, an individual with a dominant phenotype is crossed with a homozygous recessive individual to determine its genotype.

In a test cross, the individual with an unknown genotype is crossed with a homozygous recessive individual.

A person with blue eyes must have the genotype bb, as blue is recessive.

In Mendel's experiments, yellow seed color was observed to be the dominant trait in pea plants.

In Mendel's experiments, yellow seed color was observed to be dominant over green seed color.

The probability of obtaining a homozygous recessive offspring (aa) from a cross between two heterozygous parents (Aa x Aa) is 25%.

The genetic makeup of an organism is referred to as its genotype.

A dihybrid cross involves two traits, and AaBb x AaBb is an example of such a cross.

Transgenic inheritance is not a recognized pattern of inheritance; it refers to organisms that have been genetically modified.

The genotype 'AA' represents a homozygous dominant individual.

A phenotype is the observable characteristic, such as brown eyes.

The term 'phenotype' refers to the physical appearance of an organism.
