Name two factors that determine the phenotype of a trait?
genes
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
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
Hybrid corn is produced that is resistant to bacteria infection and is highly productive What might have been the phenotypes of the two parents?
If bacterial resistant, highly productive corn is produced, the phenotypes could be - Resistance to a pathogen might just be from a single gene. Productively are the result of several genes, often termed "Quality Trait Loci" or "QTLs." Combining several genes from each parent leads to Hybrid vigor, where the hybrid has better productively than its best parent.
List by order size the following gene gene pool genome chromosome?
order from largest to smallest: gene, genome, chromosome, DNA, gene pool
When one gene expresses itself over another the former gene is called what?
The gene that expresses itself over the other is Dominant. The former gene is recessive.
When one gene expresses itself over another the former gene is said to be the DNA?
The gene that expresses itself over the other is Dominant. The former gene is recessive.
When one gene expresses itself over another the former gene is said to be the?
Recessive
When a gene expresses itself in the presence of a contrasting gene it is said to be?
When a gene expresses itself in the presence of a contrasting gene, it is said to be dominant. Dominant alleles mask the effects of recessive alleles, leading to the phenotype associated with the dominant gene being observed in the organism. This concept is fundamental to Mendelian genetics, where the interaction between alleles determines observable traits.
What are some examples of a hybrid gene?
hybrid genotype
If an individual expresses a dominant disease will the children always inherit the disease?
Not always. It depends if the individual is a hybrid- meaning they have both the dominant and the recessive gene. They can pass on the recessive gene instead of the dominant one, and assuming the other parents also passes on the recessive gene, the child will not inherit the disease.
What is a hybrid gene?
A hybrid gene is a gene that is formed from a combination of two different genes. It can be made by recombinant DNA technology. Hybrid genes possess at least one characteristic of both the genes combined.
What two different alleles a hybrid?
A hybrid individual inherits one allele from each parent for a particular gene. These alleles can be different versions of the same gene, which result in the hybrid individual having a combination of traits from each parent.
In a heterozygous organism one gene shows itself while the other gene is?
In a heterozygous organism, one gene may be dominant while the other is recessive. The dominant gene expresses its trait, overshadowing the effect of the recessive gene, which does not manifest in the organism's phenotype. This relationship is a fundamental principle of Mendelian genetics, where the dominant allele can mask the presence of the recessive allele in a heterozygous pairing.
Any gene located on a sex chromosome is called?
The answer to your question is Hybrid.
What are represor proteins?
Repressor is protein that can regulate gene expression. When it binds to the operator, the gene expression tuned off and when it detaches from the DNA the gene expresses as normal. This phenomeno of gene regulation is known as operons.
Which letter or pair of letters would represent the genes of a hybrid?
A hybrid organism can inherit different versions of a gene, one from each parent. In genetics, one letter per gene is typically used to represent each version (allele) of a gene. For example, if the gene for flower color has two possible versions (alleles) - red and white - they may be represented by the letters R and W. So, the gene/alleles for a hybrid could be represented by a letter or pair of letters, depending on the specific gene and its alleles.
