How is a trait that is determined by multiple genes different from one that is determined by multiple alleles?

Multiple genes: these are polygenetic and have more alleles than mult. alleles. Therefore, mult genes have more variation. When two genes are on the same chromosome there is a greater chance for them to appear together on the same gamete and on the same offspring so they are said to be linked.

When you have 2 identical alleles for a trait you are group of answer choices?

If an organism contains two identical alleles for a particular trait, the genotype for this trait is said to be homozygous.

How are two traits on different chromosomes inherited?

When two traits are on different (non-homologous) chromosomes, how are they inherited? Indecently, of one another depending on choice and random alignment of meiosis.

Do the alleles have to be the same for each trait?

Although an individual gene may code for a specific physical trait, that gene can exist in different forms, or alleles. One allele for every gene in an organism is inherited from each of that organism’s parents.

What is the difference between a trait that has multiple alleles and a trait that is controlled by multiple genes?

The majority of human genes are thought to have more than two normal versions or alleles. Traits controlled by a single gene with more than two alleles are called multiple allele traits. An example is ABO blood type….Multiple Allele Traits.

Genotype	Phenotype (blood type)
IAIB	AB

What does it mean if there are two different alleles for a trait?

An organism which has two different alleles of the gene is called heterozygous. Phenotypes (the expressed characteristics) associated with a certain allele can sometimes be dominant or recessive, but often they are neither.

What is having two different alleles for a trait?

Heterozygous: Having two different alleles for a trait.

What are the different ways that a trait may be inherited?

autosomal dominant – where the gene for a trait or condition is dominant, and is on a non-sex chromosome. autosomal recessive – where the gene for a trait or condition is recessive, and is on a non-sex chromosome. X-linked dominant – where the gene for a trait or condition is dominant, and is on the X-chromosome.

How are the alleles of a gene different from each other?

Alleles of a particular gene differ from each other on the basis of certain changes i.e. mutations in the genetic material segment of DNA or RNA. Different alleles of a gene increases the variability or variation among the organisms.

How can someone have two different alleles of the same gene?

Since diploid organisms have two copies of each chromosome, they have two of each gene. Since genes come in more than one version, an organism can have two of the same alleles of a gene, or two different alleles. This is important because alleles can be dominant, recessive, or codominant to each other.

What are the seven traits observed by Mendel?

Seven traits observed by Mendel Trait 1. Flower color Trait 2: Seed color Trait 3: Flower position Trait 4: Pod shape Trait 4: Stem height Trait 6: Pod color Trait 7: Seed shape

What did Mendel’s experiments show about the nature of genetic inheritance?

In his experiments, Mendel was able to selectively cross-pollinate pure bred plants with particular characters and observe the result over many generations. This was the foundation for his inferences about the nature of genetic inheritance.

What is Mendel’s law of cross-pollination?

While experimenting with cross-pollinating plants which produced yellow or green pea seeds, Mendel found that the offspring of first generation (f1) always had yellow seeds. But, the offspring of second generation (f2) regularly has a 3:1 ratio of yellow to green seeds. This 3:1 ratio also followed in later generations (f3, f4, f5…) also.

What did Mendel discover about cross breeding pea plants?

Mendel selectively cross-bred over 28,000+ common pea plants for many generations and he discovered that certain characters show up in offspring without any mixing of parent characteristics. For example, the pea flowers are either purple or white and intermediate colors do not appear in the offspring of cross-pollinated pea plants.
