What does DD genotype mean?
Background: The DD genotype gene is a linkage marker for an etiologic mutation at or near the angiotensin-converting enzyme gene and has been associated with increased risk for the development of coronary artery disease, left ventricular hypertrophy and left ventricular dilation after myocardial infarction.
What would the phenotype be for DD?
Susan’s genotype is “Dd”, so she is considered HETEROZYGOUS (has two different alleles for a specific gene). Although Susan has both the allele “D” to make dimples and the allele “d” in her genotype, her phenotype is the presence of dimples….
| t | t | |
|---|---|---|
| T | Tt (tall) | Tt (tall) |
What is FF phenotype?
Genotype is the genetic makeup of an individual eg Ff or FF. Phenotype is the physical appearance eg carrier of cystic fibrosis. A Recessive allele only has an effect if you inherit two copies eg ff (cystic fibrosis). If two carriers have children, each child has a 25% of being born with the disease.
What genotype is EE?
heterozygous
The person with the Ee genotype is heterozygous for the trait, in this case, free earlobes. An individual is heterozygous for a trait when it has two different allelic forms of a particular gene. The heterozygous individual received one form of the gene from one parent and a different allele from the other parent.
What is the genotypic ratio for DD?
When gametes are combined to form new individuals (in the square), we see that 1/4 of the offspring should be DD, 2/4 (or 1/2) should be Dd, and 1/4 should be dd. These are the possible genotypes of the next generation, and the probabilities of each occurring.
What are the genotypes for DD and DD?
DD and dd are the genotypes, with dd being recessive and DD being dominant. They are genotypes that directly impact risk factors for coronary artery disease and other circulatory problems. Home Science Math and Arithmetic
What is the phenotype of a person with dimples?
Susan’s genotype is “Dd”, so she is considered HETEROZYGOUS (has two different alleles for a specific gene). Although Susan has both the allele “D” to make dimples and the allele “d” in her genotype, her phenotype is the presence of dimples.
How is the phenotype and genotype of an organism determined?
Genotype refers specifically to the genes, not the traits; that is, the raw information in an organism’s DNA. Genotype is determined by the makeup of alleles, pairs of genes responsible for particular traits. An allele can be made up of two dominant genes, a dominant and a recessive gene, or two recessive genes.
How are Sally and Susan dimples gene homozygous?
He is HOMOZYGOUS(has 2 identical alleles for that gene) for the dimples gene. Sally’s genotype is “dd”, so she is also considered homozygous. Susan’s genotype is “Dd”, so she is considered HETEROZYGOUS(has two different alleles for a specific gene).
