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.
A trait which always appears when it is present is called what kind of trait?
It is called a dominant trait
Trait of an organism that can be masked by the dominant by the dominant form of a trait?
A trait that masks another trait is called dominant, or a dominant trait.
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 describes a trait that is covered over or dominated by another form of the trait and seems to disappear?
The trait that is being masked is recessive, and the trait that is doing the masking is dominant.
The trait observed in the first generation when parents that have different traits are bred?
A dominant trait.
What is a trait that is overridden by another trait?
Dominant- Covers up another form of a trait. Recessive- Is covered up by a dominant trait.
The form of a trait that appears to mask another form the same trait is called what?
Dominant Trait
A trait that appears or is expressed in the f1 generation is what?
the dominant trait
Not expressed when the dominant form of a trait is present?
The recessive trait isn't present when the dominant form of the trait is there. Whenever a trait is dominant trait is present it ALWAYS takes over the recessive one. the law of Dominance
What does it mean to have a dominant trait?
In genetics, a trait is considered dominant when it determines a phenotype over a recessive trait. For example, AA is crossed with AA to make Aa, Aa, Aa, and Aa. If "A" is the dominant trait and "a" is the recessive trait, then since this cross produces heterozygous progeny, they will all show the dominant phenotype. A dominant trait is just how it sounds, it dominates over recessive traits when they are both present.
In a hybrid individual the trait that is covered and not expressed is the what trait?
recessive
What are dominant traits?
dominant trait is a genetic trait which may cause a hereditary condition
