Gregor Mendel called them factors, or traits.
What else can I help you with?
What happened in mendels experiments when a pea received two different alleles for the same trait?
Unless the alleles are codominate (which Mendel did not have in pea plants), one will be dominate and will be what you see (phenotype) and one will be recessive and you will not see it.
Is the following statement true or false only pea plants that have two recessive alleles for short stems will be short?
False. Pea plants can have short stems if they have two recessive alleles for short stems, but they can also have short stems if they have a combination of dominant and recessive alleles that result in a short stature.
In pea plants the peas produced may be green or yellow with yellow being the dominant form of the allele. What would be the phenotype of a pea plant that is heterozygous for the alleles?
yellow peas
What was gregor mendels theory of heredity based on?
Gregor Mendel's theory of heredity was based on his experiments with pea plants, where he observed distinct patterns of inheritance for different traits. He proposed the principles of dominant and recessive traits, the segregation of alleles during gamete formation, and the independent assortment of different traits during inheritance. Mendel's work laid the foundation for modern genetics.
How do dominant and recessive alleles affect an offsprings phenotype?
The traits inherited depends upon the alleles that have been passed on from the father and mother.The traits that are exhibited is called as the phenotype. Dominant allele needs only one copy to be expressed.For example in a pea plant "T" represents the tall dominant allele and "t" the short recessive allele .TT - when there are two dominant alleles the pea plant will express the tall trait. The pea plant is tall.Tt - when there is one dominant and one recessive allele the pea plant will still express the tall trait.In this case the dominant allele masks the recessive allele and the pea plant is still tall.tt - when there are two recessive alleles the pea plant will express the recessive trait and the pea plant is short.For a recessive trait to show up there should be a pair of recessive alleles.

How did gregor Mendel become famous?
He discovered dominant and recessive alleles. He also bread and tested 29,000 pea plants

In pea plants the peas produced may be green or yellow with yellow being the dominant form of the allele. What would be the phenotype of a pea plant that is heterozygous for the alleles?
yellow peas
If a pea plant has two alleles YY. what is its genotype?
The genotype of a pea plant with two alleles YY is homozygous dominant. This means that both alleles for the trait in question are the same and dominant. In this case, the plant will express the dominant trait associated with the YY genotype.
In pea plants the peas produced may be green or yellow with yellow being the dominant form of the allele . What would be the phenotype of the pea plant that is heterozygous for the alleles?
yellow peas
In pea plants tall (T) plants are dominant over short (t) plants. If a heterozygous (Tt) pea plant is crossed with a homozygous dominant (TT) pea plant all of the resulting pea plants should be tall (?
Dominant Allele
How many alleles controlled flower color in mendels experiments?
In Mendel's experiments with pea plants, flower color was primarily controlled by a single gene with two alleles: one for purple flowers (dominant) and one for white flowers (recessive). This simple inheritance pattern allowed Mendel to observe the ratios of flower colors in the offspring, leading to his foundational principles of genetics.
What was the original generation pea plants in mendels experiment called?
P1 or parental

How dominant or recessive alleles for the trait of stem height determine whether a pea plant will be tall or short?
The dominant trait for height in a pea plant is tall (TT or Tt). The only instance in which a pea plant will be short is if it carries both recessive alleles (tt).
