If a couple with normal phenotypes get married and have a child then what is the chance that the child will develope achondroplasia?
People with achondroplasia can be born to parents who don't have the condition. This is the result of a new mutations. New gene mutations leading to achondroplasia are associated with the paternal age effect (over 35 years old). Studies have demonstrated that new gene mutations for achondroplasia are exclusively inherited from the father and occur during spermatogenesis.

How many phenotype can result from the cross TtYy x ttyy?
Four phenotypes can result from the cross TtYy x ttyy. The four possible phenotypes are: TY, Ty, tY, and ty. This is because the offspring can inherit different combinations of alleles for the two genes, resulting in different trait combinations.
How did the distribution of phenotypes change over time?
The distribution of phenotypes can change over time due to natural selection, genetic drift, and gene flow. Natural selection can favor certain phenotypes that provide a reproductive advantage in specific environments, causing those phenotypes to become more common. Genetic drift and gene flow can also alter phenotypic frequencies by random chance or through the movement of genes between populations.
Does the genotypes and phenotypes are likely to occur at different frequencies in both the original and reduced population because of genetic drift?
Yes, genetic drift can cause changes in the frequency of genotypes and phenotypes in a population over time. In a small population experiencing genetic drift, certain genotypes and phenotypes may become more common by chance, while others may be lost. This can lead to differences in the distribution of traits between the original and reduced population.
A homozygous blue flower BB is crossed with a homozygous white flower bb What are the possible genotypes and phenotypes of the offspring?
The possible genotypes of the offspring are Bb (heterozygous blue) and bb (white). The possible phenotypes are blue and white flowers. Each offspring will inherit one allele from each parent, resulting in a 50% chance of being blue (Bb) and 50% chance of being white (bb).
A form of dwarfism caused by an autosomal dominant allele?
A form of dwarfism caused by an autosomal dominant allele is achondroplasia. It is characterized by short stature, disproportionately short limbs, and other physical abnormalities. Individuals with this condition have a 50% chance of passing on the allele to their offspring.
Is achondroplasia hereditary?
yes, achondroplasia is hereditary and if one of a parent has it you have 50% chance to inheriting it.
What type of inheritance is achondroplasia?
Achondroplasia is inherited by the parents as a dominant disease. It occurs from a defect in the FGFR3 gene. It usually occurs spontaneously. if both parents have the disease they have a 25% chance of having a normal sized child, a 50% chance of having a child with Achondroplasia, and a 25% chance of the child getting both genes from each parent which results in death.
How many phenotype can result from the cross TtYy x ttyy?
Four phenotypes can result from the cross TtYy x ttyy. The four possible phenotypes are: TY, Ty, tY, and ty. This is because the offspring can inherit different combinations of alleles for the two genes, resulting in different trait combinations.
How can a wide range of phenotypes increase the chance that some individuals will survive in a changing environment?
by natural selection.
Is Alzheimer's Disease a genetic disorder?
Yes and no. see if your grand parents had it, there could be a chance that you might develope alzheimer's disease, but you might also develope alzheimer's disease just from old age. So from that, under any circumstances, there is the chance of developing alzheimer's anytime after the 40-50 y/o mark.

No chance
Probability of getting married and having children?
A man has an 81 percent chance to get married if they live the United States before the age of 40. A woman has an 86 percent chance of getting married.
Why some phenotypes are more common in a population than others?
Phenotypes that are more advantageous for survival and reproduction in a given environment are more likely to be passed on to future generations, leading to their increased frequency in a population over time. This process is driven by natural selection, where individuals with beneficial traits have a higher chance of passing on their genes. Additionally, genetic drift, gene flow, and mutations can also influence the frequency of phenotypes in a population.
Does the genotypes and phenotypes are likely to occur at different frequencies in both the original and reduced population because of genetic drift?
Yes, genetic drift can cause changes in the frequency of genotypes and phenotypes in a population over time. In a small population experiencing genetic drift, certain genotypes and phenotypes may become more common by chance, while others may be lost. This can lead to differences in the distribution of traits between the original and reduced population.
