When parents differ in only one trait, such as flower color in pea plants, they are often used in genetic studies to understand inheritance patterns. For example, if one parent has purple flowers (dominant trait) and the other has white flowers (recessive trait), their offspring will exhibit a mix of traits based on Mendelian inheritance. This scenario can help illustrate concepts like dominant and recessive alleles, as well as the phenotype and genotype ratios in the resulting generation.
Yes, buy only if the parents are heterozygous for the trait and if the trait is dominant.
A cross between parents using only one trait called a monohybrid
If the trait is exhibited in the offspring of two normal parents, it suggests that the trait is a dominant one. This means that only one copy of the gene is needed for the trait to be expressed. Alternatively, the trait could be influenced by a de novo mutation that occurred in the germ cells of one of the parents.
The term for breeding parents when only one trait is being investigated is called a "monohybrid cross." In this type of genetic cross, one trait is analyzed to observe how it is inherited from one generation to the next, typically focusing on dominant and recessive alleles. This approach helps in understanding the inheritance patterns of that specific trait.
Mendel's Law - The first law of Mendel states that "In a cross of parents that are pure for contrasting traits, only one form of the trait will appear in the next generation. Offspring that are hybrid for a trait will have only the dominant trait in the phenotype."
A monohybrid cross considers one pair of contrasting traits (or alleles) in an offspring resulting from the mating of individuals that differ in only one trait. This type of genetic cross allows predictions about the inheritance pattern of a specific trait based on the known genotypes of the parents.
No
Yes, buy only if the parents are heterozygous for the trait and if the trait is dominant.
If a disease or trait came from the parents then that's "hereditary". On the other hand, if a disease or trait did not came directly from the parents then that can only mean it was "acquired"
A cross between parents using only one trait called a monohybrid
Only if they have 2 parents with the trait(gene) or disease
A recessive trait only appears in an organism when it is homozygous for that trait, meaning it has two copies of the recessive allele. This occurs when an organism inherits the recessive allele from both parents.
Recessive trait. This type of trait is only expressed when the individual has two copies of the gene for that trait, one from each parent. If only one copy is present, the dominant trait will be expressed.
If the trait is exhibited in the offspring of two normal parents, it suggests that the trait is a dominant one. This means that only one copy of the gene is needed for the trait to be expressed. Alternatively, the trait could be influenced by a de novo mutation that occurred in the germ cells of one of the parents.

A recessive trait can only be passed along if both parents carry at least one of the recessive genes to the child. If both parents manifest the trait (that is, if both parents have both recessive genes), then the child will manifest (that is, carry both recessive genes and display) the recessive trait. If one parent manifests and the other parent only carries the trait (that is, carries one dominant and one recessive gene) then the child will definitely carry and have a 50% chance of manifesting. If both parents carry the recessive, the child is 25% likely not to carry the trait at all, 50% likely to carry and 25% likely to manifest the trait.
