When mendel crossed true breeding tall plants with true breeding short plants all the offspring were tall because?
Tallness is a dominant trait and shortness is a recessive trait according to Mendel's principles of inheritance. When true breeding tall plants (homozygous dominant) are crossed with true breeding short plants (homozygous recessive), all offspring inherit one dominant tall allele, resulting in them being tall.
If a male plant that is true breeding for the recessive trait for wrinkled seeds is crossed with a female plant that is true breeding for the dominant trait for round seed what shap will the offspring?
When a male plant that is true breeding for the recessive trait of wrinkled seeds (genotype: rr) is crossed with a female plant that is true breeding for the dominant trait of round seeds (genotype: RR), all the offspring will inherit one allele from each parent, resulting in the genotype Rr. Since the round seed trait is dominant, all offspring will display the round seed phenotype.
When gregor mendel crossed true bleeding tall plants with true bleeding short plants plants all the offspring were tall because?
When Gregor Mendel crossed true-breeding tall plants with true-breeding short plants, all the offspring were tall because the tall trait is dominant over the short trait. In this cross, the tall plants contributed a dominant allele, while the short plants contributed a recessive allele. Since the presence of just one dominant allele is sufficient to express the tall phenotype, all the F1 offspring exhibited the tall trait. This foundational experiment established key principles of inheritance.
Is this true or false The allele AA is homozygous dominant?
True. The allele AA represents a homozygous dominant genotype, meaning that both alleles at a particular gene locus are the same and both are dominant. In this case, the individual has two copies of the dominant allele A.
What is the dominance -recessive interaction of an allele pair?
This depends on the type of dominance relationship. You can have true dominance, in which case if the allele pair contains a dominant allele, the dominant trait will be expressed. In this case the recessive trait will only be exhibited if both alleles are recessive. A second case is that of codominance. In this case, two alleles are codominant, so if you have one of each, both traits will be expressed. A third case is that of incomplete dominance. In this case, if you have a dominant and a recessive allele, you will get a trait which is a mixture of both traits. A good example is when you breed a red flower and a blue flower and get a purple flower as progeny. Other things, like dominance series, also exist. However this information should answer your original question.
Is it true that an organism with a dominant allele for a particular form of a trait only exhibits the trait sometimes?
true
Is it true that mendel assumed that a dominant allele had masked the corresponding recessive allele in the f1 generation?
Yes, Gregor Mendel's principle of dominance stated that in the F1 generation, the dominant allele would mask the expression of the corresponding recessive allele. This means that only the dominant trait would be observed in the offspring.

True or False In heterozygous individuals only the recessive allele is expressed?
In heterozygous individuals, only the dominant allele is expressed. The recessive allele is present, but not expressed
What is true of the allele pair of someone with a genotype TT?
The allele pair of someone with a genotype TT is homozygous dominant.
A living thing that shows a dominant trait may be homozygous dominant or homozygous recessive for the trait true or false?
False because a living thing that shows a dominant trait can not be homozygous recessive. If it is homozygous recessive it will show recessive trait. A living thing that shows dominant trait may be homozygous dominant or hetrozygous.
If a male plant that is true breeding for the recessive trait for wrinkled seeds is crossed with a female plant that is true breeding for the dominant trait for round seed what shap will the offspring?
When a male plant that is true breeding for the recessive trait of wrinkled seeds (genotype: rr) is crossed with a female plant that is true breeding for the dominant trait of round seeds (genotype: RR), all the offspring will inherit one allele from each parent, resulting in the genotype Rr. Since the round seed trait is dominant, all offspring will display the round seed phenotype.
Mendel crossed a true green podded plant with a true yellow podded plant. All the offspring from this cross had green pods. Green is the?
Green is the dominant trait in this cross. Mendel's results demonstrate that when a dominant allele (for green pods) is present, it masks the effect of the recessive allele (for yellow pods), resulting in all offspring exhibiting the dominant phenotype. Thus, the true yellow podded plant contributes a recessive allele that does not express in the presence of the dominant green allele.
When 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?
Dominant.
