What else can I help you with?
How can the homozygous dominant genotype be written?
A dominant Allele is written YY or Homo dominant. That is completely dominant and no recessive. Yy is half or hetro dominant. Forgive me for it has been a while since i talked and brushed on this. Homo recessive is yy. You should and would never see yY. it is written Yy.
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 is the name of inheritance pattern in which both alleles are expressed equally?
It depends on what you mean by "both are expressed". In order for both alleles to be expressed, both alleles must be dominant alleles. If one allele is recessive, it will be masked. If you are talking about alleles that are co-dominant, then both alleles would be expressed together. Ex: Red x white = red and white flower If you are talking about incomplete dominance, then both alleles are seen as a blend of both in the offspring. Ex: red x white = pink flower If you are talking about multiple alleles (like in human blood typing), then you can see 2 alleles expressed together. Ex: Type A x Type B can produce AB blood type.
What is the difference between incomplete dominance and codominance?
co dominance is when there is no dominant or reccessive traits just lie in in incomplete dominance the diffrence is in co dominance the are mkore chromosomes
What happens in Mendel's experiments when a pea plant received two different alleles for the same trait?
Unless the alleles are codominate (which Mendel did not have in pea plants), one will be dominate and will be what you see (phenotype) and one will be recessive and you will not see it.
The outward expression of a gene?
The outward expression of a gene is determined by the alleles. Alleles come and pairs, and the pairings can be heterozygous or homozygous. For homozygous (both alleles are the same) phenotypes, the trait you see is the same as the alleles. For example, if both alleles are for a white flower, the flower will be white. There are different outcomes for heterozygous (one dominant allele, the other recessive) phenotypes. In complete dominance (the most common), the dominant allele is the the trait you see. For example, the flower has an allele for red (dominant) and white (recessive), it will be red because red is dominant to white. In incomplete dominance, the dominant allele is not strong enough to fully cut out the recessive so trait will be a mix of both. In the flower's case, it would be pink because white will be seen through the red. In codominance, both alleles are expressed just on different areas. The flower would have both red and white splotches.

What is the difference between dominant and recessive gene?
There are no such things as dominant and recessive genes. There are only dominant and recessive alleles. Dominant alleles are parts of a gene that present its features over the recessive allele, which is the one that is always masked by the dominant allele. The recessive allele's trait only shows if both of the alleles in a trait are recessive.
Is Recessive alleles the traits visible in the F1 generation of true-breeding organisms?
Only if the generations before were homozygous recessive as well. When doing the punnett square and you see there is a chance of having a heterozygous trait then that specie is not a purebred. The organism's offsprings must have the same physical traits.
Why is it impossible for offspring to show the recessive trait if one parent is homoygous for the dominant trait?
Because the parent with the homozygous alleles for the dominant trait can only pass on that dominant allele to its offspring and the dominant allele, if present, is always expressed.
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.
How do you know if an allele is co-dominant?
An allele is a small piece of DNA responsible for some characteristic that plugs into a gene locus (or position) along a chromosome. Suppose the particular gene locus is responsible for flower colour in some plant. There may be alleles that plug in amongst the plant population for red or yellow flowers. Since chromosomes are paired, several combinations are possible. Both alleles may be red so the flower will be red and similarly for yellow. If there is a red allele and a yellow allele you may either get orange flowers but if one allele is dominant over the other the flower colour will be either red or yellow depending on which allele is dominant. If the red allele is dominant over the yellow there will be more red flowers. If it was only as simple as this three quarters of the flowers would be red and onequarter would be yellow. For two possible alleles with red dominant over yellow, there are four combinations:- R R Red flowers R Y Red flowers Y R Red flowers Y Y Yellow flowers
What is the name of inheritance pattern in which both alleles are expressed equally?

Information on hand clasping genetic traits?
Well there are some genetic traits controlled by a couple of alleles (hand calsping, tongue rolling, ear lobe attachment, etc.). and there are other controlled by many alleles (as hair color, eye color, skin color, height, etc.). Hand clasping is one trait that, so far as I know, some people believe it is controlled by just one pair of allels other people think it is controlled by many of them. I prefer to believe hand clasping just has 2 alleles. Considering this, we can say that one of this 2 alleles is Dominant and another recessive, as usually, however there are some cases when both alleles are dominant. -What do I mean by dominant and recessive? Well, this means that if both are in the same locus for that genetic trait (or gene, it is the same) the dominant will be the one that will expressed in the person carrying these alleles for this gene (or genetic trait, it is the same =P). So in the cae of hand clasping, if you join the fingers of your hand (I do not how to explin it exactly), you should see wheter your right or your left thumb is up. If your left thumb is above your right that is the dominant trait expressing. And if your right thumb is above , well you have the reccesive allele expressing. I hope I had contribute. =) Giorgio.

Why are alleles important to genetics?
Alleles are important in genetics because they are different versions of the same gene that can result in different traits. Alleles contribute to genetic diversity and are responsible for the variations we see within a population. Understanding how alleles interact and are inherited helps us study inheritance patterns, genetic diseases, and evolutionary processes.
What is the difference between incomplete dominance and codominance?
co dominance is when there is no dominant or reccessive traits just lie in in incomplete dominance the diffrence is in co dominance the are mkore chromosomes
Is a condition in which neither of the two genes pair masks the other?
This is called co-dominance. Both alleles are expressed. For example, if white and red in a flower are co-dominant, the offspring will have both red and white petals in a flower. See link below:
