Multifactorial inheritance describes the situation were more than one gene affects a single trait. Environmental factors can also contribute to the single trait.
Its possible. A single gene defines a single protein.
In meiosis, each gamete receives one allele for each gene, ensuring genetic diversity and random assortment of traits in offspring. This process helps create unique combinations of genes in gametes, leading to variability in traits among individuals.
Homozygous recessive for that trait. This means that both alleles at that specific gene locus are the same and code for the recessive trait.
A widow's peak is a dominant trait, so even if a person has both the widow's peak and the straight hairline trait, only the widow's peak will be visibly apparent.
yes it could......... when it happens its called polygenic inheritance
Its possible. A single gene defines a single protein.
A genetic locus is the specific location on a chromosome where a particular gene is located. It serves as a unit that determines the expression of a specific trait due to the presence or absence of alleles at that locus.
A polyallelic trait is a trait controlled by multiple alleles (variants of a gene) at a single gene locus. This means there are more than two possible alleles that can influence the trait's expression, resulting in a range of phenotypic variations. This can lead to a complex inheritance pattern.
an Allele.
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."
A trait is generally expressed phenotypically. An allele is one of a pair alleles at the same locus...often referred to as a gene. An allele is present whether expressed or not. A single gene locus will have two alleles in an individual, but there may be more than 2 alleles for this locus in the population. General human blood groups are an example of this with A,B, O as the primary alleles and several other less common ones...(like M) present in the population.
An example of a human trait caused by a single gene with multiple alleles is the ABO blood group system. This system is determined by the presence of different alleles at the ABO gene locus, specifically A, B, and O alleles. The combinations of these alleles result in four possible blood types: A, B, AB, and O, illustrating how multiple alleles can influence a single trait.
phenotype
Genes for a certain trait are located on specific regions of chromosomes. Each gene occupies a particular locus on a chromosome, and variations in these genes can result in different expressions of the trait. The specific location of a gene on a chromosome is referred to as its genetic map position.
In meiosis, each gamete receives one allele for each gene, ensuring genetic diversity and random assortment of traits in offspring. This process helps create unique combinations of genes in gametes, leading to variability in traits among individuals.
A 3:1 phenotypic ratio (Mendelian inheritance).
yes its called pleiotropy
