If two genes in a gene pair are for the same trait what will that trait be?

The question should be "If two alleles for a gene are the same, what phenotype will the organism have?"
Answer: If the two alleles are for the dominant phenotype, the organism will exhibit the dominant phenotype. If the two alleles are for the recessive phenotype, the organism will have the recessive phenotype.

What is polygeny?
Inheritance in which more than one gene pair affects the appearance of a particular trait. Polygenetic inheritance refers to the non-Mendelian form of inheritance in which a particular trait is produced by the interaction of many genes.
Name two factors that determine the phenotype of a trait?
genes
What does being heterozygous for some genetic trait mean?
the 2 alleles of the gene for the trait are different on the 2 homologous chromosomesBeing heterozygous for a trait means that they have different alleles for a trait. For instance: Tt would be heterozygous and TT or tt would be homozygous because they are both eitehr little or big t's.it mean the gene is not pure or for example suppose a person is blood group A but actually he is having A and O; because O is recessive trait the gene express the A trait instead, making the person having blood group A.
The outward appearance of a trait is?
The outward appearance of a trait is called a phenotype.the alternative form of a gene is called an "allele." Alleles occur at the same locus on homologous chromosones, thus govern the same trait. This term is sometimes used sysnonymously with "gene."
What are dominant and recessive genes?
A dominant gene- A gene That is "stronger" than a recessive geneA recessive gene- A gene that must have 2 of the same to have that look.ex: A gene for being tall=T (CAPITAL T)A gene for being short=t(lowercase t)TT=TallTt=talltt=shortThe GENES WHICH ARE EXPRESSED IN THE PROGENY ARE CALLED DOMINANT AND WHICH DO NOT EXPRESS ARE CALLED RECESSIVE
What is the name each gene in a pair of genes that might or might not carry the same information about a trait?
the name is hybrids
What is the name for each gene in a pair of genes that might or might not carry the same info about a trait?
the name is hybrids
What is name of the two genes one on each chromosome of a pair that control the same trait are called?
genes
What is polygeny?
Inheritance in which more than one gene pair affects the appearance of a particular trait. Polygenetic inheritance refers to the non-Mendelian form of inheritance in which a particular trait is produced by the interaction of many genes.
Word describing the two chromosomes in a pair that have genes that code for the same trait?
Homozygous.
Which of these is a gene that does not express itself and is concealed by the presence of another gene of the same trait?
A hypostatic gene is one that can by hidden by other genes.
How are dominant trait and recessive trait the same?
They are both used to format your genetic make up.
What are different versions of the same gene called?
The chromosomes in a pair carry the same genes in the same places. There are different versions of the same gene. These different versions of the same gene are called alleles.
Which one pair of genes is the weakest?
No genes are "weaker" than any others, they are all made of the same stuff.
What trait is is expressed when two diffrent genes for the same trait are present?
A dominant trait is expressed when two different genes for the same trait are present.
What are the characteristics of polygenic traits?
Polygenic means that multiple genes created the same trait. The skin color gene is polygenic because multiple genes will give you the same trait.
What is the relationship between genes and alleles?
The gene loci are the sites where the alleles reside on the DNA strand. Alleles at the same gene locus on each chromosome pair will determine the phenotypic expression of that gene pair. Of course this explanation is incomplete when more complex interactions between alleles come into play
