Non-Mendelian Inheritance Patterns

The pattern of inheritance for a trait where the heterozygous genotype shows an intermediate phenotype is called ______.

In human blood type inheritance, the pattern of inheritance involving multiple alleles is observed, where the A, B, and O alleles determine blood type is called ______.

The pattern of inheritance involving the contribution of multiple genes to produce a single trait is known as ______.

When both alleles of a gene are fully expressed in the heterozygous condition, the pattern of inheritance is called ______.

When one gene's expression is influenced by the expression of another gene, it is referred to as ______.

In a study of skin color in humans, it is observed that skin color is determined by the cumulative effect of multiple genes located on different chromosomes. Individuals with a combination of alleles from multiple genes may exhibit a wide range of skin tones. This pattern of inheritance is known as ______.

Tay-Sachs disease is a rare genetic disorder characterized by the absence of an enzyme necessary to break down lipids called gangliosides. Individuals who inherit two copies of the defective allele typically do not survive past early childhood due to severe neurological degeneration. This condition is an example of ______.

Ichthyosis is a skin disorder characterized by dry, scaly skin. The condition is caused by mutations in the steroid sulfatase gene (STS) located on the X chromosome. This is an example of ______.

In sweet peas, flower color is determined by two genes: the P gene (purple pigment) and the W gene (white pigment). However, if an individual is homozygous recessive for the P gene (pp), the expression of the W gene determines the flower color. This interaction is called ______.

In a certain species of reptiles, scale color is determined by two genes, A and B. Gene A controls the production of pigment, while gene B controls the distribution of pigment. Reptiles with a bb genotype will have no pigment in their scales, regardless of the genotype at gene A. This is an example of ______.

In a certain species of reptiles, scale color is determined by two genes, A and B. If two reptiles with the genotype AaBb are crossed, the probability of having an offspring with unpigmented scales is ______.

The key difference between autosomal and sex-linked disorders is that autosomal disorders are caused by genes located on ______, while sex-linked disorders are caused by genes located on sex chromosomes.

A couple has one child affected by albinism, an autosomal recessive disorder. If both parents have normal pigmentation and there is a 50% chance their child becomes a carrier of the disorder, the correct genotype of the parents is ______.

If two organisms with genotypes Aa and aa for albinism mate, the percent chance of having an affected son is ______.

Huntington's disease is an autosomal dominant disorder. An affected individual who is homozygous for the disease mates with a normal person. The probability of having an affected child is ______.

Huntington's disease is an autosomal dominant disorder. If an affected individual who is homozygous mates with a normal person and they have 10 children, the number of children expected to be affected is ______.

Huntington's disease is an autosomal dominant disorder. An affected individual who is homozygous for the disease mates with a normal person. Therefore, the probability of having a daughter who is affected by the disease is ______.

______ is the application of biological principles, processes, and systems to develop products and technologies that benefit society, industry, and the environment.

Organisms that have been modified through genetic engineering techniques are best defined as ______.

The primary goal of recombinant DNA technology is to ______ DNA to create new genetic combinations.

______ are commonly used to cut DNA molecules at specific sequences in recombinant DNA technology.

A ______ is a vector for transferring DNA into a host cell in recombinant DNA technology.

In recombinant DNA technology, the purpose of using selectable markers is to distinguish ______ cells from non-transformed cells.

A pattern of inheritance where the heterozygous genotype results in a phenotype that is a mix of both homozygous phenotypes showcases ______.

When a single gene influences multiple distinct phenotypic traits, such as in Marfan syndrome, it is known as ______.

Traits that are influenced by multiple genes resulting in a continuous range of phenotypes demonstrate ______.

In shorthorn cattle, the roan coat color (a mix of red and white hairs) is an example of ______, as neither red nor white is dominant.

Genes located on the same chromosome that tend to be inherited together are referred to as ______.

When the expression of one gene masks or modifies the expression of another gene, you have ______.
