The former of these traits is also called a test cross.

He developed what is known as a test cross.

More simply put, test crosses determine the genotype of an individual with a dominant phenotype.

Additive effects are often calculated by genotyping and phenotyping offspring of a genetic test cross.

Steve Jenkins knocked the ball back to Gary Murphy, who fired a testing cross into the area.

Test crosses involve breeding the individual in question with another individual that expresses a recessive version of the same trait.

One constraint remains that seedlings may still carry the apomictic trait, and it is necessary to have progeny from a test cross to determine this.

The visitors had no answer to Antonio Valencia, who dominated the right flank with a conveyor belt of testing crosses and neat passes.

By performing test crosses, he determined that all the yellow mice were heterozygotes and that the yellow colour coat was the dominant phenotypic trait.

Conron tried the test cross with a Standard Poodle named "Harley" and a Labrador retriever named "Brandy."

The ratios in test cross are always equal e.g; if a heterozygous white(Yy)is crossed with homozygous yellow,then 2 gametes formed will be Yy and yy.

In genetics, a test cross, first introduced by Gregor Mendel, is used to determine if a group exhibiting a dominant trait is homozygous or heterozygous for that trait.

George's forte was tricky and clever wing play, whereby he consistently gained sufficient, room to put across a steady stream of accurate and testing crosses, from which other forwards regularly benefited.

The phenotype here would still be purple and long but a test cross of this individual with the recessive parent would produce progeny with much greater proportion of the two crossover phenotypes.

They used a line of purebred labrador retrievers developed at the University of Oregon Health Sciences Center in Portland Oregon and used a series of test crosses and experimental breeding to test their hypothesis.

To select the most promising parents for hybrid production, test crosses conducted in various environments are required, because the variance of their specific combining ability under differing environmental conditions is the most important component in evaluating their potential as parents to produce promising hybrids.

In some sources, the "test cross" is defined as being a type of backcross between the recessive homozygote and F1 generation or F2 generation crossed with recessive parent is said to be a test cross.
