Sentences with phrase «recessive allele»

Because the sire and dam share 2 recent common ancestors, CMS is likely the result of recessive alleles inherited identical by descent (IBD).

My family history doesn't have much in the way of rare inherited syndromes, but that doesn't mean I'm not a carrier of one or two recessive alleles for something like cystic fibrosis.

The relatively high estimates of the frequencies of the unfavourable recessive alleles in each breed, especially for hip dysplasia, suggest that it would be possible to gain considerable genetic progress by selection against a major gene.

Whereas human forms of CMS are often caused by compound heterozygosity, low levels of genetic diversity within purebred dog populations make simple recessive alleles more common.

Recessive traits, such as shortness in pea plants, are only expressed when two recessive alleles meet up.

MAIN Dominant and recessive alleles Heterozygous and homozygous Regular Afl and mini plenaries Exam questions differentiated by scaffolding Self assess and Peer assess activities Whiteboard activities Harry Potter Challenge PLENAARY Quiz Extension Exam Q PLenary

Both the dominant and recessive alleles detected.

Many of endearing unique traits in dog breeds today are the result of homozygous recessive alleles being forever paired together in the future generations.

The most recessive allele, when homozygous, results in hair that is yellowish, as in Golden Retrievers and yellow Labradors.

Over the last few decades, inbreeding and loss of genetic diversity have resulted in an increase in the expression of recessive alleles as well as inbreeding depression, which affects things like fertility, puppy mortality, and lifespan.

Although the visual effect can be the same, it is easy to confuse this with the subtle hint of bronze (liver) that shows through in coats of some black dogs that carry an incompletely - masked recessive allele (one of the gene pair) for «a dilute» such as liver - chocolate.

The above diagram indicates that at the A locus, there might be either the most dominant «solid» pattern allele, As, that allows for dominant black to be expressed, or else the ay recessive allele that codes for yellow - red and does not allow any black regardless of what is called for on other loci.

The most - recessive allele in this series is e, restricting (refusing) any expression of black.

To my occasional frustration, by chance alone, a litter of 10 or 12 mice can be born without a single animal having the desired combination of recessive alleles.

As part of their study of genetics, students in Shannon Dziwanowskis seventh - grade science class at Csar Chvez Academy Middle School in Detroit, Michigan, spend the first minutes of class reviewing a worksheet on dominant and recessive alleles, which are alternative forms of genes.

Dog has two copies of the recessive allele, and does not have the mask allele.

The dog has a Red / Yellow coat, and will always pass on the recessive allele to all potential offspring.

Two copies of the recessive allele are present.

Animal Genetics currently offers a test for the D - Locus to determine how many copies of the recessive allele a dog carries.

The dog will always pass on a copy of the recessive allele to any offspring.

Dog carries one copy of the mask allele and one copy of the recessive allele.

If the gene was present in the original Labrador Retrievers, it is possible that the trait remained hidden for many generations due to the fact that it requires two recessive alleles to be present at the same time, and the d allele may have been very rarely occurring.

Each gene location has an associated dominant and recessive allele.

The dominant gene is represented by a capital letter, «S», and the recessive allele uses lower case, «s».

The other gene having the recessive allele, while the first one retains the dominant, produces the blue (gray) Doberman, whereas the least likely combination of both color genes having recessive alleles produces fawn, which is a light tan color, often called Isabella.

The traditional color, produced when one or both genes have the dominant allele, is commonly referred to as black or black and rust (also called black and tan), while the most common variation, due to both genes having the recessive allele, produces what is called a red or red and rust Doberman in America and a «brown» Doberman in the rest of the world, which is primarily deep reddish - brown with rust markings.

Shiloh has inherited a recessive allele for a genetic trait or mutation.

Both the dominant and recessive alleles are detected.

For a lab to have the silver color that has become so popular over the last several years, this D pair must have two recessive alleles (dd) and results in a dilute color of the solid color.

Dogs with any of the recessive alleles may have congenital hereditary deafness.

The recessive allele, ky, allows the basic patterns of the A locus to be expressed.

Congenital hereditary deafness in most dog breeds is associated with 1 of 2 classical pigmentation genes responsible for white or light skin and fur coloration: piebald and merle.1 The pigment locus S has 3 recessive alleles: Irish spotting, piebald, and extreme piebald; dogs with the dominant allele have solid color.

The test Vetgen offers detects the presence or absence of the recessive allele that results in long coats when present in two copies, and as such allows dogs with short coats that carry a hidden «long coat» allele to be detected.

Dogs homozygous for 1 of the recessive alleles have white coloration.

Genetic transmission of deafness in dogs with the recessive alleles of this pigment gene, such as the Dalmatian (which is homozygous for sw), is less clear.

Three recessive alleles are recognized: Irish spotting (si), piebald (sp), and extreme white piebald (sw).

Piebald is a recessive allele of the S gene, where the dominant allele is expressed as a solid color.

If a dominant and recessive allele are paired, the dominant trait can override the recessive trait or result in a «mixed» trait that becomes its own phenotype, such as the chocolate Labrador Retriever.

But every Labrador Retriever has both sets of genes which can come in any combination of capital and lowercase letters — dominant or recessive alleles.

Sometimes, When two recessive alleles are paired, they get superpowers of their own, as with yellow Labradors.
