What is recessive gene and dominant gene?
A dominant gene is always expressed if present, and the recessive gene is only expressed with the homozygous recessive genotype. For example, if the dominant gene is red (represented by the letter R) and the recessive gene is white (represented by the letter r), then a homozygous dominant organism's genotype will be RR, and its phenotype will be red. If the organism is homozygous recessive, then the genotype will be rr and the phenotype will be white. If the organism is heterozygous, then the genotype will be Rr, and the organism will be red.
How is the combination of genes important in determining the inheritance of biological traits?
The genes an organism contains is called the organism's genotype.
If an animal with 2 dominant genes for a trait has offspring with an animal with 2 recessive genes for same trait their offspring can only have what?
Their offspring will have dominant genes. However, if these offspring have offspring with an amimal with recessive genes, the recessive genes will show up.
What includes an organism's unseen recessive genes?
An organism's unseen recessive genes are included in its genotype, which is the complete set of genetic information inherited from its parents. While these recessive alleles may not be expressed in the organism's phenotype (the observable traits), they can still be passed to offspring. If an organism carries two copies of a recessive allele, or one copy alongside a dominant allele that does not mask it, the trait can become visible in subsequent generations. Thus, recessive genes play a crucial role in inheritance and genetic variation.
What type of allele masks the expression of the recessive allele?
Two recessive alleles can not take over a dominant allele because there are only two alleles in a pair. This can only happen if there is a mutation because the dominant always takes over the recessive.
What do you call an organism that possesses one dominant and one recessive genes for a single trait?
heterozygous
What do you call oransim that posssses two dominant or two recessive genes for a single trait?
Homozygous dominant for two dominant genes or homozygous recessive for two recessive genes.
The weaker of two genes is called what?
The weaker of two genes is called the recessive gene. In the presence of a dominant gene, the recessive gene is not expressed in the organism's phenotype.
Dominant and recessive genes?
Dominant genes are shown for example as T recessive genes are shown as t if there is a dominant and recessive gene (Tt) then your child will get the dominant one this is called heterozygous. Meaning that they have two different genes for a trait such as curly hair and straight hair. There is also being homozygous (TT or tt) the only way your child could recieve a recessive gene such as left handednes, is if the two parents were carrying a recessive gene along with their dominant one or if they both were carrying two reccesive genes. the childs probable genotype can be explaind a lot better with a Punnet Square. I hope this wasn't too confusing.:-)
Do dominant genes affect recessive genes?
The dominant genes take over, and then the recessive genes hide away
Which genes are dominant and which are recessive?
Dominant genes are always expressed in preference to recessive genes in cased where both genes are present.
Genes that prevent the other gene from showing traits are called?
Dominant genes. Dominant genes are always expressed in an organism's phenotype when present, masking the expression of recessive genes.
What is recessive gene and dominant gene?
A dominant gene is always expressed if present, and the recessive gene is only expressed with the homozygous recessive genotype. For example, if the dominant gene is red (represented by the letter R) and the recessive gene is white (represented by the letter r), then a homozygous dominant organism's genotype will be RR, and its phenotype will be red. If the organism is homozygous recessive, then the genotype will be rr and the phenotype will be white. If the organism is heterozygous, then the genotype will be Rr, and the organism will be red.
What is an organism with one dominant and one recessive gene for a trait?
An organism with one dominant and one recessive gene for a trait is called a heterozygote. In this case, the dominant gene will be expressed in the organism's phenotype, while the recessive gene will not be expressed unless the organism inherits two copies of the recessive gene.
How is codominance difference from dominant and recessive relationship?
Codominance is when 2 dominate genes appear in the phenotype of an organism. (some one else can tell you what dominate and recessive genes are)
What are the difference between dominant and recessive genes?
Dominant genes will cover up recessive genes. Take a simplified version of eye color for example. Brown is dominant and blue is recessive. Someone might have the allele for both brown and blue, but their eyes will be brown because of the dominent brown gene. If there are two parents that carry the recessive gene, neither will be blue eyed, but they will have a chance of having a blue eyed child if both pass on the recessive gene.
An organism with two different alleles for a single trait is said to be heterozygous?
A heterozygous is a hybrid of genes. It has a dominant and recessive gene. The dominant gene covers over the recessive trait, making the individual have the dominant trait. (trait are alleles...) or apex ans:two
