Answer:
The phenotypically dominant organism is the individual in question in a test cross.
The former of these traits is also called a test cross.
The purpose of a test cross is to determine if this individual is homozygous dominant or heterozygous.
Test crosses are used to test an individual's genotype by crossing it with an individual of a known genotype.
Test crosses involve breeding the individual in question with another individual that expresses a recessive version of the same trait.
Finally, he performed " test crosses " ( backcrossing descendants of the initial hybridization to the initial true-breeding lines ) to reveal the presence and proportions of recessive characters.
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.
If all offspring from the test cross display the dominant phenotype, the individual in question is homozygous dominant; if half the offspring display dominant phenotypes and half display recessive phenotypes, then the individual is heterozygous.
"We found that we could not test cross-training sneakers fast enough to say anything about models that would still be on the market when we published, " said Leslie Ware, a senior editor, referring to a type of shoe designed for different activities.
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.
