Genes located on different chromosomes will be inherited independently of each other. Mendel observed that, when peas with more than one trait were crossed, the progeny did not always match the parents. This is because different traits are inherited independently – this is the principle of independent assortment.

When genetically based traits are inherited independently from each other this is known as quizlet?

If two individuals who are heterozygous for the sickle-cell disease mate, their offspring: both b) and c) are correct. When genetically based traits are inherited independently from each other, this is known as: Mendel's law of independent assortment.

What does it mean if alleles are homozygous?


Homozygous is a genetic condition where an individual inherits the same alleles for a particular gene from both parents.

What is incomplete dominance?

Abstract. Incomplete dominance results from a cross in which each parental contribution is genetically unique and gives rise to progeny whose phenotype is intermediate. Incomplete dominance is also referred to as semi-dominance and partial dominance.

What is the difference between homozygous and heterozygous genes?

Heterozygous refers to having inherited different forms of a particular gene from each parent. A heterozygous genotype stands in contrast to a homozygous genotype, where an individual inherits identical forms of a particular gene from each parent.

What do you mean by H * * * * * * * * * and heterozygous?

Homozygous and heterozygous are terms that are used to describe allele pairs. Individuals carrying two identical alleles (RR or rr) are known as homozygous. While individual organisms bearing different alleles (Rr) are known as heterozygous.

How are traits inherited?

Inherited traits are passed from parent to offspring according to the rules of Mendelian genetics. Most traits are not strictly determined by genes, but rather are influenced by both genes and environment.

What is the genotype for black chickens?

In some chickens, the gene for feather color is controlled by codominance. The allele for black is B and the allele for white is W. The heterozygous phenotype is known as erminette.

Is height dominant or recessive?

A pea plant could have a copy of the height gene that coded for "tall" and a copy of the same gene that coded for "short." But the tall allele is "dominant," meaning that a tall-short allele combination would result in a tall plant.

What is meant by epistasis?

Epistasis is genetic phenomenon that is defined by an interaction of genetic variation at two or more loci to produce a phenotypic outcome that is not predicted by the additive combination of effects attributable to the individual loci.

What is genetic allele?

An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent.

What is the relationship between genes and alleles?

DNA is arranged on chromosomes in segments called genes. One gene tells the cell how to make one protein. Different variations of a gene are called alleles. Each parent passes one allele to the child for each gene.

What term refers to a trait that is overshadowed by another trait when both are present?

recessive allele. the allele of a gene that is overshadowed; will only seen in the homozygous recessive genotype. law of independent assortment. States each pair of alleles segregates independently of each other pair of alleles during gamete formation; any combination of traits (most of the time)

What is test cross quizlet?

Test cross. A genetic cross in which a test organism showing the dominant trait is crossed with one showing the recessive trait; used to determine whether the test organism is homozygous dominant or heterozygous.

What are the three ABO blood type alleles quizlet?

Remember: The ABO blood group gene codes for different antigens on the surface of a person's red blood cells. There are three alleles for this gene: IA, IB,and i. Depending on a person's alleles, they can have A antigens, B antigens, both, or none.

What is Codominance inheritance?


Codominance is a relationship between two versions of a gene. Individuals receive one version of a gene, called an allele, from each parent. If the alleles are different, the dominant allele usually will be expressed, while the effect of the other allele, called recessive, is masked.

Is being hairy a dominant gene?

There are two types of genetic traits: dominant and recessive. ... If you happen to be a hairy person, you can guarantee that your children will also inherit this particularly fuzzy trait because it's caused by a dominant gene.

Is black hair dominant or recessive?

Black hair is the darkest and most common of all human hair colors globally, due to larger populations with this dominant trait. It is a dominant genetic trait, and it is found in people of all backgrounds and ethnicities.

Can two short parents have a tall child?

Yes, short parents regularly do have a tall child. Complete nutrition during development also results in taller children, though not taller than the determining genetic factors. ... Some genetic traits are dominant, recurring in each generation.

When chickens with splashed white feathers are crossed?

When chickens with splashed white feathers are crossed with black-feathered birds, their offspring are all slate blue (Blue Andalusian).

What type of inheritance do two alleles have if their traits blend together?

One exception is incomplete dominance (sometimes called blending inheritance) when alleles blend their traits in the phenotype. An example of this would be seen if, when crossing Antirrhinums — flowers with incompletely dominant "red" and "white" alleles for petal color — the resulting offspring had pink petals.

What does FR and W mean in genotypes?

The white fur coat allele would be represented by an F (for "fur") with a "W" subscript and a brown fur coat allele would be represented by an F with a "B" subscript.

How and when did humans know that traits are inherited from parents?

However, there was no scientific way to predict the outcome of a cross between two particular parents. It wasn't until 1865 that an Augustinian Monk named Gregor Mendel found that individual traits are determined by discrete "factors," later known as genes, which are inherited from the parents.

How did you inherit your individual traits?

Parents pass on traits or characteristics, such as eye colour and blood type, to their children through their genes. ... The two alleles in a gene pair are inherited, one from each parent. Alleles interact with each other in different ways. These are called inheritance patterns.

How is genetic information inherited?

Genetic information is passed from generation to generation through inherited units of chemical information (in most cases, genes). Organisms produce other similar organisms through sexual reproduction, which allows the line of genetic material to be maintained and generations to be linked.
