When mendel crossed a strain of tall pea plants with a strain of short pea plants he observed that all the f1 generation were tall this suggest that?
the tall trait was controlled by a dominant factor.
How did Mendel know the the tall pea plants in the first generation had a hidden factor for shortness?
By "test cross" you can know whether it homozygous dominant or heterozygous dominant...in homozygous both alleles code for the dominant trait, in heterozygous one allele is recessive (what you called a "hidden factor"). To perform the test cross, cross a homozygous recessive with the first generation. Lets suppose tall pea tree in the first generation is hetrozygous dominant (Xx) and has alleles X (dominant) and x (recessive). When we cross it with homozygous recessive (xx) X x x :Xx xx x :Xx xx we get half offspring showing dominant trait (Xx) and half showing recessive (xx). If the first generation was homozygous (which is not possible) the result would be X X x: Xx Xx x: Xx Xx all the offspring showing dominant trait and it doesn't really happen when we cross the first generation with homozygous recessive. It means that the genotype of first generation is heterozygous (has a hidden factor or a recessive allele x). Note:You must know what the recessive and dominant allele means...In presence of a dominant allele, recessice character is not expressed but it is present is heterozygous. If both alleles are recessive (homozygous recessive) then the recessive trait is expressed. If both the alleles are dominant (homozygous dominant) obviusly the dominant trait is showed by the individual.
What is a sadle mule?
A saddle mule is a mule used for transportation or riding, were as a pack mule is a mule used solely for transporting luggage rather then people.
What is a name for a mule handler?
Mule Skinner
Which animals are sterile Donkeys or mules or can mule impregnant another mule?
Mules are sterile, a mule is the offspring of a donkey and horse, therefore sterile. A male mule can mate with a female mule, but will never get her pregnant.
What is a dominate trait?
Dominant trait is a genetics term. A dominant trait is one which will be expressed if one of the parents has the gene for that trait. A recessive trait is one that will be expressed only if both parents carry the trait.
What type of trait prevents the other type from being seen?
A recessive trait. When a recessive allele is with a dominant allele, only the dominanate trait can be seen.
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.
What is a trait that masks a trait called?
A trait that masks another trait is called a dominant trait. This means that when an organism carries both dominant and recessive alleles for a particular gene, only the dominant trait will be expressed in the phenotype.
A trait that appears or is expressed in the f1 generation is what?
A trait that appears or is expressed in the F1 generation is considered dominant. Dominant traits will manifest themselves in the offspring when at least one parent carries the dominant allele for that trait.
The form of a trait that appears to mask another form the same trait is called what?
The form of a trait that appears to mask another form of the same trait is called the dominant trait. Dominant traits will be expressed over recessive traits in a heterozygous individual.
What is an observable trait of an organism that can mask a recessive trait?
The observable characteristic are called the genotype and any dominant trait can mask the recessive. An example would be Black Angus cattle can actually carry a red recessive trait because black is the dominant trait in cattle breeding
Is the trait of raising one eyebrow dominant or recessive?
The trait of raising one eyebrow is considered to be a dominant trait.
What does it mean that an organism is homozygous dominant for a trait?
Homozygous Dominant for a trait means that an organism has two dominant alleles for that trait. Here's an example: Trait: Widow's Peak Widow's Peak allele: Dominant (D) No widow's peak allele: Reccessive(d) Homozygous Dominant (DD) Homozygous Reccessive (dd) Heterozygous (Dd)
In a hybrid individual the trait that is covered and not expressed is the what trait?
recessive
In which offspring does a dominant trait appear?
A dominant trait will appear in offspring that inherits at least one copy of the dominant allele from either parent. If an individual has two different alleles for a trait (one dominant and one recessive), the dominant trait will be expressed.
When a trait is not expressed when paired with a dominant allele is the definiton of?
The trait that is not expressed when paired with a dominant allele is known as a recessive trait. It is masked by the dominant trait in individuals carrying both alleles.
