Down syndrome is a genetic disorder that adversely affects both genotype and phenotype. Down syndrome effects on phenotype include slow mental and physical development of an individual.
Down syndrome is characterized by a combination of phenotypic features that includes typical dysmorphic features and mental retardation. Congenital malformations of the heart (30-40% of the patients) and gastrointestinal tract are common. Congenital absence of teeth has been reported in 23 to 47%

∙ 11y agoDown syndrome is a somatic disorder that results in an additional chromosome 21 in the conceptus (embryo). The resulting child is 2N+1 or 47 chromosomes.
The parents are generally 2N.
Down Syndrome parents generally have normal 2N children.

Which can you physically see genotypes or phenotypes?
You can see the phenotype. A good way to remember is that a photograph is what you see. The genotype is the graphic representation of the trait.
How many different phenotypes can be produced from intercrossing parents of genotype AaB1B2?
two
What is the pthenotype for each genotype?
Genotypes are the specific allele combinations that an individual contains pertaining to a certain trait. Phenotypes are what is expressed due to the genotype. (recessive/dominant/codominant)
What best describes phenotypes?
traits. your welcome! yall lil cheaters! lol (:
Determine the phenotypes for the genotype yellow body color is dominant to blue?
well it could be yellow for like yy of b
Which can you physically see genotypes or phenotypes?
You can see the phenotype. A good way to remember is that a photograph is what you see. The genotype is the graphic representation of the trait.
What is the probability of genotypes and phenotypes?
What is the probability that any of the offspring between individuals with the genotype AABbCcddEE will have the genotype AABBCCddEE
Did mankind affected sugar gliders genotype or phenotypes?
nope
How are the genotype and phenotype of parents related to the genotype and phenotypes of offsprings?
The parents can pass on only the alleles of their genotypes to their offspring. Therefore, the offspring genotypes and phenotypes are dependent solely upon the alleles inherited from the parents.
Which could be the genotype for a male suffering from Klinefelter's syndrome?
The genotype for a person suffering with Klinefelter's syndrome is XXY.
How are phenotypes and genotypes related to natural selection?
Natural selection favours phenotypes that bestow a reproductive advantage, thereby increasing the frequency of alleles (genotype) producing those phenotypes.
How differences in genotypes cause variations in phenotypes?
Phenotypes are the traits expressed by the genotype. So, for blood type, a person can have A and i alleles (genotype). However, in the phenotype, since i is recessive, only the A will be expressed, and the person will have an A blood type.
What genotypes cause Klinefelter's syndrome?
The only genotype to cause Klinefelter's syndrome is XXY.
How many different phenotypes can be produced from intercrossing parents of genotype AaB1B2?
two
What genotype must the person have who possessed the recessive phenotypes?
The genotype is homozygous recessive or the recessive trait is on the X chromosome and has no corresponding allele on the Y chromosome.
How are Genotype phenotype different?
Phenotypes are the traits expressed by the genotype. So, for blood type, a person can have A and i alleles (genotype). However, in the phenotype, since i is recessive, only the A will be expressed, and the person will have an A blood type.
When trying to find an unknown genotype you must perform a?
Perform a test cross. Cross the organism with an organism with a homozygous recessive genotype and use the phenotypes of the offspring and a Punnett square to figure out the unknown genotype.
