In the F2 generation in Mendel's experiment's the ratio of dominant to recessive traits was?
3:1 homozygous dominant, heterozygous dominant, heterozygous dominant and homozygous recessive.
Is an organism that is homozygous for many recessive traits at a disadvantage?
It depends on the trait. A dominate trait is not always an advantage, and a recessive trait is not always at a disadvantage.
What is a genotype composed of?
Genotype is the genetic make up of an organism both expressed (phenotype) and unexpressed.Example: AaeeDndn is the genotype which includes unexpressed (recessive) alleles a and dn.Expressed dominant traits A and Dn as well as expressed recessive traits (ee). Note that expressed recessive traits have to be homozygous.
How do you identify a homozygous ressive genotype?
See if the parent organisms have the same trait as the offspring. Those traits have to be recessive.
What are the names of the genotypes?
Homozygous dominant (Ex:AA) Heterozygous (Ex:Aa) Homozygous recessive (Ex:aa)
What are the types of homozygous traits you can get from punnet squares?
AA: Homozygous dominant aa: Homozygous recessive
In the F2 generation in Mendel's experiment's the ratio of dominant to recessive traits was?
3:1 homozygous dominant, heterozygous dominant, heterozygous dominant and homozygous recessive.
What do you call traits that can only be seen if the individual has both alleles for it?
Homozygous recessive.
What is the difference between homzyguos and heterozyous?
Homozygous recessive: is when the genes are both recessive Homozygous dominant: is when the genes are both dominant (traits show) Heterozygous dominant: is when one gene is dominant and one is recessive (traits show) Heterozygous recessive: is the same as heterozygous dominant but the dominant genes are inactive
What is the phenotype of a purebred recessive?
A recessive trait is known as the characteristic that is the outward expression of the gene. Recessive traits can be masked by dominant traits but are still present if the gene is present in the organism.
A cross between homozygous purple-flowered and homozygous white-flowered pea plants results in offspring with purple flowers This demonstrates?
A homozygous purple flower and a homozygous white flower having offspring that are purple is an example of dominance. Traits that yield to other traits is referred to as recessive. So in this case Purple was the dominant trait and White was the recessive trait.
Is an organism that is homozygous for many recessive traits at a disadvantage?
It depends on the trait. A dominate trait is not always an advantage, and a recessive trait is not always at a disadvantage.
What type of letter do you use to represent a dominant trait?
Capital letter such as R for dominant and r for recessive trait
What is a genotype composed of?
Genotype is the genetic make up of an organism both expressed (phenotype) and unexpressed.Example: AaeeDndn is the genotype which includes unexpressed (recessive) alleles a and dn.Expressed dominant traits A and Dn as well as expressed recessive traits (ee). Note that expressed recessive traits have to be homozygous.
How do you identify a homozygous ressive genotype?
See if the parent organisms have the same trait as the offspring. Those traits have to be recessive.
What genotypic condition must be present for a recessive trait to be visible?
if the ratio had more recessive traits, like if you made a punnit square and you saw that there were more of the recessive traits (BB bb bb bb) then you know that the most common trait is the recessive one "bb" (considered as homozygous recessive ( i think))
What are the names of the genotypes?
Homozygous dominant (Ex:AA) Heterozygous (Ex:Aa) Homozygous recessive (Ex:aa)
