"Heterozygus" and homozygus" are adjectives that describe the relationship of genes, they are not genes themselves.

What does homozygus mean?
Homo means same so in a Punnett square, if one organism's gene is either BB or bb- the same- it is homozygus. When it is heterozygus, it would be Bb- or different 2 genes. Homozygus is an individual having two identical alleles of a particular gene or genes and so breeding true for the corresponding characteristic.
Actual gene make up of an organism is its?
i dont know lollool
What is a homozygus?
When two cells have the same gene type then they are considered homozygous.
Heterozygus phenotypes show qualities of both alleles?
Heterozygous phenotypes show qualities of both alleles is called co-dominance.
Is the trait TT heterozygous or homozygous?
Yes.A homozygous genotype is a gene with two identical alleles. Recessive genes are represented by a lowercase letter. Thus, a homozygous recessive genotype would be two identical genes with lowercase letters.
Can b-positive parents have child with o-positive blood?
Believe it or not, the answer is YES! Each parent carries what are known as alleles for blood protiens, which can be A, B or O. A and B are considered Dominant, and if one of them is present, the persons blood type will be the same as the domininant alelle. O is recessive, and unless neither A nor B are present for the other allele, the "O" will not be "visible". Folks that have AB blood type have codominance (one of each dominant allele). The rest of us who are either A or B (I'm A!) have one of the following combinations: AA (homozygus) Ao (Heterozygus) BB (Homozygus) Bo (Heterozygus). It's tough to draw a table in this space, but here's how it works when two people have a child (at least as far as blood type goes!) THe Mom's alleles are listed on the top here (for this example, they don't have to be) and the Dad's are listed down the left: Here we're looking at a heterozygus "A" Dominant mom and a heterozygus "B" dominant dad. Mom and dad each "donate" an allele to their child, and it can occur in one of four ways: the four possible ways are inside the square A o B AB Bo o Ao oo What this tells us is that with an A mom and a B dad, there's a 25% chance the baby will be AB, 25% chance B, 25% chance A, and 25% O. That said, here's some possibilities for the questioner: Even though I've never met them or tested their blood, I can be 100% sure that IF they truly are the parents of a type "O" baby, then they each are heterozygus dominant for the B allele (see below) B o B BB Bo o Bo oo That tells us that with two "B" parents, there's a 25% chance the offspring will be "O". As to the "Positive" or "Negative" aspect of blood type, that's a reference to the Rh factor. This is a little more complicated, but as long as one parent is positive, the baby will be positive. If both parents are positive, there's no doubt the baby will be too. So, if the questioner had said that they had an "O-" baby, I'd have to blow the whistle on that one! Congrats on the new kiddo!
What color is a person with AAbb genotype?
if a man were non- hemophiliac and he marries a woman whois homozygus for nan-hemophilia,give the possible genotypes of the children
Can a type A plus and a B have a type O child?
yes, as a matter of fact, they can. if both parents are heterozygus for A and B blood, then there is a chance that they can have a type O child
Are polygenic genes dominant genes?
Polygenic genes are usually dominant genes.
Are the fathers genes always the dominant genes?
No - the father's genes are not always the dominant genes.
What are defective genes?
defective genes are genes that are defective
Does prokaryotes have genes?
Of course they have genes. They need genes for survival and reproduction.
