The trait observed in the first generation when parents that have different traits are bred?
The trait observed in the first generation when parents with different traits are bred is known as the dominant trait. This trait is expressed in the offspring because it masks the expression of the recessive trait.
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.
What is the second generation of off spring from a cross of two organisms?
The second generation of offspring from a cross of two organisms is known as the F2 generation. In this generation, the genetic traits from the original parent organisms are recombined and expressed in new combinations. The F2 generation results from the mating of two F1 individuals, which are the first generation offspring of the original parents.
The gene that is fully expressed when two different alleles are present is the?
heterozygous gene. In this situation, both alleles are different and both are expressed, resulting in a blending or mixing of their traits.
An allele is dominant in a heterozygote when it is?
expressed in the phenotype even when paired with a different allele.
If the F2 generation expressed a trait in a 3.1 ratio the F1 generation MUST be heterozyous for that trait?
True
The trait observed in the first generation when parents that have different traits are bred?
The trait observed in the first generation when parents with different traits are bred is known as the dominant trait. This trait is expressed in the offspring because it masks the expression of the recessive trait.
For a recessive trait to be expressed in a generation of offspring an individual must be a?
Homozygous
What kind of behavior is genetically preprogrammed?
Instinctual behaviors, such as reflexes and some animal mating rituals, are believed to be genetically preprogrammed. These behaviors are innate and do not require learning or prior experience to be expressed.
Mendel referred to the characteristic that was expressed in the hybrid F1 or first filial generation as?
Mendel referred to the characteristic expressed in the hybrid F1 generation as the dominant trait. This trait masks the expression of the recessive allele in the heterozygous individual.
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.
What views that the older generation of Australia expressed of the involvement of Australia in the Vietnam war?
USS ARIZONA
What characteristic was true of mendel's f1 generation plants?
Mendel's F1 generation plants showed only one of the two traits present in the parental generation. This indicated that the trait expressed in the F1 generation was dominant, while the other trait was recessive.
What is the second generation of off spring from a cross of two organisms?
The second generation of offspring from a cross of two organisms is known as the F2 generation. In this generation, the genetic traits from the original parent organisms are recombined and expressed in new combinations. The F2 generation results from the mating of two F1 individuals, which are the first generation offspring of the original parents.
What type of allele is known for skipping a generation?
Recessive alleles are known for skipping a generation. This is because the phenotype associated with a recessive allele is only expressed when an individual inherits two copies of the recessive allele, one from each parent. If one parent carries the allele but does not exhibit the trait, it can appear to "skip" a generation before being expressed.
What did the generation writers express in their work?
Groups of young American writers who expressed feelings of disillusionment in the American society.
What did Gregor Mendel call the traits that disappear in the first generation?
Gregor Mendel called the traits that disappear in the first generation recessive traits. These traits are not expressed in the offspring when there is a dominant trait present.
