Mendel concluded that each trait was controlled by two factors, which we now understand as alleles, based on his experiments with pea plants. He observed that each parent contributes one allele for each trait to the offspring, leading to the concept of dominant and recessive alleles. This foundational idea formed the basis of Mendelian genetics, demonstrating how traits are inherited in predictable patterns. Mendel's findings laid the groundwork for our understanding of heredity and genetic variation.
What else can I help you with?
Based on his experiments Mendel concluded that each trait was controlled by two what?
Based on his experiments, Mendel concluded that each trait was controlled by two alleles, one inherited from each parent. These alleles can be dominant or recessive, determining how traits are expressed in the offspring. Mendel's work laid the foundation for the principles of inheritance in genetics.
Based on his experiments Mendel concluded that each trait was controlled by two?
invisible "factors" - now called genes.
How many choices were there for each pea plant trait mendel examineed?
Mendel examined one trait at a time in his pea plant experiments. For each trait, he had two choices: the dominant allele and the recessive allele. Therefore, there were two choices for each pea plant trait that Mendel examined.
Which of Mendel's laws states that only one parental allele for each trait is included in a sex cell?
Mendel's law of segregation states that only one allele for each gene is passed into an organism's gametes. This means that each parent contributes one allele for a particular trait to their offspring.
2 alleles for each trait separate during meiosis according to who?
The principle that two alleles for each trait separate during meiosis is known as Mendel's Law of Segregation, formulated by Gregor Mendel in the 19th century. This law states that during the formation of gametes, the alleles for a trait segregate from each other so that each gamete carries only one allele for each trait. This segregation occurs during the first meiotic division, specifically during anaphase I, when homologous chromosomes are pulled apart.

How many factors did Mendel conclude control each trait?
the plant has 2 factors for each possible trait one for each parent
How many choices were there for each pea plant trait mendel examineed?
Mendel examined one trait at a time in his pea plant experiments. For each trait, he had two choices: the dominant allele and the recessive allele. Therefore, there were two choices for each pea plant trait that Mendel examined.
Mendel called plants that received different alleles for a trait from each parent?
The answer is: hybrids
What is a principle or law of heredity which states that for each trait there are two copies of the gene or genes that are responsible for the trait?
Mendel's Law Of Segregation
Which of Mendel's laws states that only one parental allele for each trait is included in a sex cell?
Mendel's law of segregation states that only one allele for each gene is passed into an organism's gametes. This means that each parent contributes one allele for a particular trait to their offspring.

This segregation occurs during the first meiotic division, specifically during anaphase I, when homologous chromosomes are pulled apart.
What is the one thing that Gregor Mendel realized could explain the results of his experiments?
each trait had two sets of instructions one from each parent
Mendel's law of segregation states that an organism inherits two alleles for any given trait one from each parent?
Mendel's law of segregation states that each organism carries two alleles for a trait, one from each parent, and during gamete formation, these alleles segregate randomly into separate gametes. This results in each gamete carrying only one allele for a given trait.
The one thing that gregor mendel realized could explain the results of his experiments was that?
Each trait had two sets of instructions, one from each parent.
Mendel's theory says that an offspring never gets both trait-controllers from the same parent which of his laws state this?
Mendel's Law of Segregation states that each parent contributes only one allele for each trait to their offspring, and these alleles segregate during gamete formation. This means that offspring do not receive both trait-controlling alleles from the same parent.
