What are the differences between heterozygous and homozygousand how to dominate and recessive allels play a role in it?

well, homozygous means that both allels are the same exp: AA, or AA. heterozygous means that the allels are different exp: Aa, or aA. when it is dominant that means that it is either Aa, or aA in order for it to be dominant it has to have a capital letter in it. if it is recessive then it must be AA only because both the letters are lowercase. ask your teacher, or someone else you know or even look it up in the dictionary about a punnet square.

How many phenotypes can come from a heterozygous parent and a homozygous recessive parent?
Two types: A heterozygous parent (Aa) and a homoygous recessive parent (aa) can produce phenotypically dominate and phenotpically recessive offspring (with 50% genotypes Aa and the other 50% aa). If the genes are co-dominate then the offspring can have blended traits and recessive traits phenotypically.
If Genotype of a G as dominate green and g for recessive yellow what would the heterozygous look like?
the heterozygous will look like green because the green is dominant allele.
When both alleles can be observed in a phenotype the interaction is called?
When both alleles contribute to the phenotype of a heterozygous the alleles are said to show the dominate alleles and sometimes the recessive but mostly the dominate alleles
The difference between a dominate and a recessive trait is?
A trait is dominant if it continues to be expressed in the heterozygous as well as the homozygous state. Recessivetraits are only expressed in the homozygous state.
Why are recessive alleles not always expressed as the phenotype?
recessive alleles get masked to show the difference in a dominant gene and a recessive gene. the dominate genes masks the recessive genes to show that the dominate gene is more dominate or more likely to be the outcome than the reccessive gene but the masked gene is not always recessive.
What contains both a dominate trait and a recessive trait?
heterozygous?
What is a gene pair that consists of a dominate allel and a recessive allel?
That is called heterozygous or it is called a hybrid.
What do you call a organism that possesses one dominate and one recessive genes for a single trait?
heterozygous
What do you call an organism that possesses one dominate and one recessive genes for a single trait?
heterozygous
How many phenotypes can come from a heterozygous parent and a homozygous recessive parent?
Two types: A heterozygous parent (Aa) and a homoygous recessive parent (aa) can produce phenotypically dominate and phenotpically recessive offspring (with 50% genotypes Aa and the other 50% aa). If the genes are co-dominate then the offspring can have blended traits and recessive traits phenotypically.
What is it called having a dominate and recessive allele?
If an individual has one recessive allele and one dominant allele, they are known as heterozygous. The dominant trait will be expressed.
What is heterozygous dominate genotype?
It's actually just heterozygous. That means that one allele is dominant and one allele is recessive. The result is a dominant trait, but the recessive gene may come back in future generations.
If Genotype of a G as dominate green and g for recessive yellow what would the heterozygous look like?
the heterozygous will look like green because the green is dominant allele.
Is AA a homozygous genotype?
homozygous = AA & AA Heterozygous = Aa
What is a genotype with one dominant and one recessive gene?
The genotype of a person with one dominate allele for a gene and one recessive would be expressed as Aa or Yy. You can use any letter you would like except one will be shown as a capital (dominate) and one as a lower case (recessive). This combination is heterozygous for that trait.
What is it when you have a gene pair that consist of two dominate alleles and two recessive alleles?
The name of the gene pair that consists of a dominant and recessive allele, i.e. (Xx) will be a heterozygous allele. In this situation, the characteristics of the dominant characteristic will mask that of the recessive allele. People have have a heterozygous genotype may be carriers for diseases that reside on the recessive allele.
An individual heterozygous for a trait and an individual homozygous recessive for the trait are crossed and produce many offspring?
The offspring has a 50% chance of the dominate trait (while being heteroygous) and a 50% chance of having the recessive trait ( homozygous recessive).
