What else can I help you with?
How can you determine the genotype of a plant that displays the dominant for a tra how can you determine the genotype of a plant that displays the dominant form of a trait?
To determine the genotype of a plant displaying the dominant form of a trait, you can perform a test cross by breeding it with a homozygous recessive plant for that trait. If any offspring display the recessive phenotype, the dominant plant is heterozygous; if all offspring show the dominant phenotype, the plant is likely homozygous dominant. This method allows you to infer the genotype based on the phenotypic ratios observed in the offspring.
What term is used to describe organisms that pass the same form of trait?
The term used to describe organisms that consistently pass the same form of a trait to their offspring is "homozygous." Homozygous organisms have two identical alleles for a particular gene, meaning they express the same trait consistently. This contrasts with "heterozygous" organisms, which have two different alleles for a gene and may express a mix of traits.
Is an organism with a recessive allele for a particular form of a trait will always exhibit that form true or false?
false
What does Gregor Mendel law of dominance state?
Mendel's law of dominance states that if you have a pair of genes then the one that shows up in the offspring is most likely the dominant gene because the dominant is passed along more often than the recessive.
How do you identify a homozygous ressive genotype?
A homozygous recessive genotype can be identified when an individual has two copies of the recessive allele for a particular gene. This means that both alleles for that gene are the same and are both the recessive form. This genotype will typically show the recessive trait associated with that allele.
What All of the offspring display only one form of a particular form?
true breeding
Will an organism with a recessive allele for a particular form of a trait will always exhibit that form?
No, an organism with a recessive allele for a particular trait will only exhibit that form if it has two copies of the recessive allele (homozygous recessive). If it has one dominant allele, it will exhibit the dominant form of the trait.

State the conclusions reached by mendel in his work on the inheritance of characteristics?
- Some "alleles" (hereditary traits) are dominant, and others are recessive. - If a pure dominant trait is bred with a recessive trait, their offspring will show 75% presence of the dominant trait, and 25% presence of the recessive trait in the F1 (first filial) generation. - If a plant with a dominant trait from the F1 generation (carrier, heterozygous dominant) is bred with a plant that shows a recessive trait, their offspring will display at 50/50 probability of dominance versus recessiveness. Thus, alleles expressing a particular trait via dominance/recessiveness, in the case of the pea plants, take the form of two alleles that combine to express a particular version. This later has been shown to be homozygous dominance/recessiveness, or heterozygous dominance.
How can you determine that genotype of a plant that displays the dominant form of a trait?
Do a testcross with a homozygous recessive plant.
Is it true that an organism with a dominant allele for a particular form of a trait only exhibits the trait sometimes?
true
What gene won't display its trait in the prescience of a dominate trait?
A recessive gene will not display its trait in the presence of a dominant trait. A recessive gene only expresses its trait when paired with another copy of the same recessive gene.

Homozygous organisms have two identical alleles for a particular gene, meaning they express the same trait consistently. This contrasts with "heterozygous" organisms, which have two different alleles for a gene and may express a mix of traits.
What is a term for one possible form of gene for a particular trait?
an alleleallele
How can you determine the genotype of a plant that display the dominant form of a trait?
Do a testcross with a homozygous recessive plant.
Is an organism with a recessive allele for a particular form of a trait will always exhibit that form true or false?
false
Roosters have genes that determine feather length Which term describes the form of a gene that produces a specific trait such as long feathers or short feathers?
Allele is the term that describes the form of a gene that produces a specific trait such as long feathers or short feathers. Traits are passed in discrete units from parents to there offspring.
