∙ 10y agoUnless 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.

∙ 10y agoWhen Mendel crossed a true-breeding short plant with a true-breeding tall plant, all the offspring were tall. Which term describes the gene for tallness?
alleles
Two alleles
If Mendel's experiments were not true breeding, then he would not be ablt to tell the recessive alleles showed up in the F2 progeny. Since the F1 generation would have showed the dominant trait regardless, the only way to show the recessive alleles carry to the F2 is to have true breeding parents.
The principle of segregation and the principle of independent assortment would apply. The principle of segregation states that each parent contributes one allele for each trait, and the principle of independent assortment states that alleles for different traits are inherited independently of each other.

Law of Dominance

Two alleles
The brothers have different alleles. They received different alleles from their parents

Mendels law of segregation states that alleles in the pair separate when gametes are formed.Mendel's law of segregation states that allele pairs separate or segregate during gamete formation, and randomly unite at fertilization.There are four main concepts related to this principle. They are as follows:A gene can exist in more than one form.Organisms inherit two alleles for each trait.When gametes are produced (by meiosis), allele pairs separate leaving each cell with a single allele for each trait.When the two alleles of a pair are different, one is dominant and the other is recessive.
The answer is: hybrids
