Explain how the inheritance of traits is controlled in organisms Use the term genes and alleles in you explanation?
The most dominant traits are the ones that control organisms genes.
What gene is always expressed?
Dominant genes will always be expressed however recessive genes would need to be inherited from both parents
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.
Are the fathers genes always the dominant genes?
No - the father's genes are not always the dominant genes.
What are the two types of alleles traits?
homozygous-2 genes that are the same ex. YY or yy heterozygous-2 genes that are different ex. Yy
How are dominant and recessive genes related?
Dominate them. Recessive alleles do not show in your phenotype unless you have two of the same recessive allele. But if you inherit one dominant and one recessive, it is the dominant that always shows in your phenotype.
How are dominant and recessive genes?
If you are talking about traits, dominant traits and recessive traits both have alleles. Dominant traits are alleles that cover up the expression of other alleles. One dominant allele with one recessive allele makes a dominant trait. Two dominant alleles together also make a dominant trate. Recessive traits are alleles that are only expressed when there is no dominant trait to cover them up. Two recessive alleles make a recessive trait. Traits can be passed over to the next generation. Two alleles together make a genotype, which is the inherited combination of alleles. Alleles: different versions of the same gene. Heredity: determined by genes. Genes: piece of DNA that shows the cell how to make a protein it needs.

The most dominant traits are the ones that control organisms genes.
The group of genes shared by members of a population including alleles for both dominant and recessive traits?
The genepool
What was the dominant alleles in Mendel's pea plants?
Gregor Mendel called them factors, or traits.
What gene is always expressed?
Dominant genes will always be expressed however recessive genes would need to be inherited from both parents
Explain how the inheritance of traits is controlled in organisms?
The inheritance of traits is controlled in organisms by genes. These genes come from either one or two parents. The alleles determine what traits are dominant or recessive in the new organism.
What are traits of alleles are controlled by?
genes
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.
How are multiple alleles different from polygenic traits?
Multiple alleles are genes that have more than two alleles. An example of this would be blood types, with ABO as three separate alleles.Polygenic traits are traits whose phenotype rely on alleles from different genes. An example of this would be hair type, which relies on genes from different parts of chromosomes.The main difference is that multiple alleles are genes with 3 or more alleles; polygenic traits do not necessarily have more alleles, but they rely on on multiple genes.
What are non-mendelian trait?
Non-Mendelian traits are:A trait with no clearly dominant alleleA trait with four allelesA trait controlled by many genes
