What is the difference fom heterozygous and homozygous recessive?
In genetics, you can either have a dominant allele (A) or a recessive allele (a). Being homozygous means that you have both of either a dominant or a recessive allele (ie you are either AA or aa). If the trait is a recessive trait, then you need to have it be homozygous recessive in order to express that trait. Hope this was helpful! :-)
What does a homozygous dominant trait look like?
A homozygous dominant trait occurs when an individual inherits two identical dominant alleles for a specific gene. The trait is fully expressed, as dominance masks recessive alleles. For example, in pea plants, homozygous dominant (RR) for flower color results in purple flowers, visibly demonstrating the dominant trait without variation. visit our website: www. chocolatekidsplayschool.org/madambakkam/
Is marfan's syndrome sex linked?
Marfan syndrome is not sex linked. It is autosomal dominant and found equally in all genders and ethnicities.
Is a tufted head on a duck a dominant gene or a resesive?
The tufted head trait in ducks is typically a dominant gene. This means that if a duck carries the tufted head gene, it is likely to express the trait, even if it also carries a recessive gene for a non-tufted head.
A animal that has two hh?
An animal with two homozygous dominant alleles (HH) would exhibit the dominant trait associated with that gene, assuming it is a simple Mendelian trait. This means the animal would show the dominant phenotype controlled by the gene in question.
Is pku disease an autosomal dominant trait?
It is an autosomal recessive trait.
Is huntington disease dominant or trait?
There is two answers, it is autosomal dominant showing incomplete dominace
Is huntingtons disease a autosomal ressesive trait?
Huntington's Disease is an Autosomal Dominant Trait, meaning that only one parent needs to pass the disease for the offspring to inherit it.
Is alzheimer's an autosomal dominant trait an autosomal recessive trait an X linked recessive trait or a chromosomal error?
Alzaymrs is ottosomal dominent
What could be the possible genotype of those that have the PTC trait?
The PTC trait is autosomal dominant so an individual with the trait could be homozygous dominant or heterozygous.
Is sickle cell anemia recessive or dominant?
Sickle cell anemia is an autosomal recessive disease. Carriers have sickle cell trait, which confers resistance to malaria.
Is Down syndrome a dominant or recessive?
Down syndrome is neither dominant nor recessive. Actually, it is considered to be an "autosomal" trait. This occurs when there is damage to the chromosome.
A trait is inherited in an autosomal dominant manner If two individuals that do not have the trait mate what percentage of their offspring would be expected to have the trait?
0. Unless there is a germline mosaicism or sporadic mutation in the fertilized embryo.
Do autosomal dominants skip generations?
Autosomal dominant traits typically do not skip generations because affected individuals usually have a 50% chance of passing the trait on to their offspring. However, the trait may appear to skip generations if carriers of the trait do not show symptoms or if there is a lack of complete penetrance.
What is the genotype of a person who is a carrier of a autosomal recessive trait?
The genotype of a person who is a carrier of an autosomal recessive trait is typically heterozygous, meaning they carry one copy of the recessive allele and one copy of the dominant allele for that trait. This would be represented as Aa, with the lowercase "a" representing the recessive allele.
Is progeria sex linked or autosomal?
Autosomal dominant
Is muscular dystrophy dominant or recessive?
autosomal dominant
