In genes what does BB Bb and bb mean?
In genetics, BB represents a homozygous dominant genotype, where both alleles are dominant. Bb represents a heterozygous genotype, where one allele is dominant and one is recessive. bb represents a homozygous recessive genotype, where both alleles are recessive.
Diffrence between homozygous and heterozygous?
They refer to the alleles in a genotype. For the basics of genetics, we can say that each allele is either dominant or recessive. Dominant is represented by an uppercase letter, and recessive a lowercase. If the genotype is AA, it is homozygous dominant. If it is aa it is homozygous recessive. If it is Aa, it is heterozygous. Simply, homozygous means that both of the alleles are the same and heterozygous means it has one of each allele.
Is AA a homozygous genotype?
homozygous = AA & AA Heterozygous = Aa
What does it mean to be heterozygous for a gene?
Being heterozygous for a gene means having two different alleles at a particular gene locus. One allele is dominant and the other is recessive. This can result in a combination of traits expressed in an individual.
What does does heterozygous mean?
Heterozygous means that you are carrying 1 dominant trait and 1 recessive trait.If an allelic pair has one dominant and other recessive gene it is called heterozygous.
In genes what does BB Bb and bb mean?
In genetics, BB represents a homozygous dominant genotype, where both alleles are dominant. Bb represents a heterozygous genotype, where one allele is dominant and one is recessive. bb represents a homozygous recessive genotype, where both alleles are recessive.

Is AA a homozygous genotype?
homozygous = AA & AA Heterozygous = Aa
Another plant is said to be heterozygous for flower color what does this mean?
homozygous means that the alleles that make up the genotype are the same, for example homozygous dominant would have two dominant alleles (RR) or homozygous recessive would have two recessive alleles (rr). the alternative would be heterozygous, where the genotype contains both a dominant and a recessive allele (Rr). so a homozygous plant would either have two dominant alleles or two recessive alleles for the seed colour. Now the way to find out whether it is homozygous dominant or homozygous recessive is to do a cross with a homozygous recessive plant and look at the seed colour (the phenotype). if the the original genotype is homozygous dominant the offspring seed colour will show the dominant seed colour becasue it will be heterozygous. But if the original plant is homozygous recessive the offspring will show the recessive phenotype.
What do you get when a heterozygous plant breads with a short plant?
I assume you mean heterozygous dominant tall and short is recessive.T = tall.t = shortTt X tt (called a test cross )1/2 Tt-----------------------heterozygous dominant1/2 tt-----------------homozygous recessive

What does does heterozygous mean?
Heterozygous means that you are carrying 1 dominant trait and 1 recessive trait.If an allelic pair has one dominant and other recessive gene it is called heterozygous.
What do you mean by hetrozygous?
Heterozygous refers to an individual having two different alleles for a particular gene. In heterozygous individuals, one allele is dominant and the other is recessive, and the dominant allele typically determines the organism's phenotype.
What do homozomes and heterozygous mean?
In genetics, you have certain traits that give you certain features. You get one part from each parent. You may have a dad with brown eyes and a mom with blue. Your dad maybe BB or Bb, and your mom bb. Like in eye color, there's brown, blue, hazel, and other colored eyes. Brown eyes is a dominant trait. So it is homozygous dominant or heterozygous (homozygous dominant = BB, heterozygous = Bb). Blue eyes are a recessive trait (homozygous recessive = bb). So, homozygous are carrying one single part of the trait, and heterozygous is carring a part of both traits.
What is the heterozygous for the A allele?
Heterozygous for the A allele means having one copy of the A allele and one copy of a different allele (e.g., a or B) at a particular gene locus. In genetics, the term heterozygous refers to an individual possessing two different forms (alleles) of a particular gene.
What is a heterozygous pair?
When the alleles of an organism for a particular character are same then it is called homozygous.Example:If the tall character of a pea plant is considered as 'T' and dwarf character as't' then the plants with TT and tt alleles are called homozygous tall and homozygous dwarf respectively.
What is the genotype and phenotype of homozygous?
Are you talking about phenotype or genotype? Phenotype is the expression of the genotype. Genotype is what you inherited. Phenotype is what you see. Homozygous is the same. Heterozygous is different. If you inherit one allele for blue eyes and one allele for brown eyes, your phenotype should be brown eyes. Your genotype would be brown eyes, blue eyes. You would have a heterozygous genotype.
