Hurlington disease is an autosomal dominant disorder that affects the nervous system if a man is heterozygous for the alleles that cause the condition and has children with a woman who lacks then?
If a man who is heterozygous for the Hurlington disease alleles has children with a woman who does not have the alleles, there is a 50% chance that each of their children will inherit the disease allele. Since Hurlington disease is autosomal dominant, inheriting just one copy of the disease allele will result in the individual being affected by the disorder.
If a man is heterozygous for the alleles that cause the condition and has children with a woman who lacks that defective allele?
If a man is heterozygous for the alleles that cause the condition and has children with a woman who lacks that defective allele, there is a 50% chance that each of their children will inherit the defective allele. This is because the man can pass on either the normal or defective allele, resulting in a 50% chance of passing on the defective allele.
Most copies of harmful recessive alleles are carried by?
Most copies of harmful recessive alleles are carried by unaffected carriers who are phenotypically normal but carry one copy of the allele. When two carriers have offspring, there is a 25% chance the child will inherit two copies of the harmful allele, leading to a genetic disorder.
What is The alteration of allelic frequencies by chance processes is known as?
Genetic drift. It refers to the random fluctuation of allele frequencies in a population due to chance events, particularly in small populations. Genetic drift can lead to the loss or fixation of alleles over time.
What are some reasons that the rat population is not a hardy-wienberg equilibrium?
There is gene flow between populations, mating is assortive and natural selection is taking place from the variations offered un by recombination and mutation. Thus, alleles are changing frequency in the population of rats and negating Hardy-Weinberg constraints.
Why does the law of independent assortment relates to crossing over and genetic linkage by?
This recombination of genes, called the crossing over of DNA, can cause alleles previously on the same chromosome to be separated and end up in different daughter cells. The farther the two alleles are apart, the greater the chance that a cross-over event may occur between them, and the greater the chance that the alleles are separated. - See more at: http://www.chacha.com/question/if-mendel's-law-of-independent-assortment-states-that-allele-pairs-separate-independently-of-each-other-during-meiosis.-how-does-this-law-relate-to-crossing-over-and-genetic-linkage#sthash.pJkZU4x9.dpuf
What is the result of crossing over?
The crossing over alleles is critical to the survival and genetic diversity of a species. The results of the random crossing over of alleles is that the offspring will have chance inheritance of certain characteristics from their parents (as opposed to being genetic clones with no diversity). The diversity of phenotypes are among the major manifestations of random crossing.
What is the parobability of inheriting two p alleles?
Ther is a 50% chance you will have two p alleles
How does crossing over and nondisjunction contribute to variation and increase genetic diversity in a population?
Crossing over is when two homologous chromosomes switch genes. This causes them to become different. Nondisjunction is when there is an incorrect splitting of a chromosome. These two types of variation result in a different set of genes each time an egg and a sperm collide by chance,
What is the relationship between the frequency of recombinant gametes and the distance between two genes on the same chromosome?
The frequency of recombinant gametes is directly related to the distance between two genes on the same chromosome. The farther apart the genes are, the higher the frequency of recombinant gametes. This is because crossing over events during meiosis are more likely to occur between genes that are further apart, leading to a greater chance of genetic recombination.
Most members of a breed are genetically?
Most of the members of a breed are genetically similar. This increases the chance that a cross between two individuals will bring together two recessive alleles for a genetic defect.
Where can you find Nicole the horse on animal crossing cityfolk?
Chance of her moving in.
Why can't probability be greater than one or less than zero?
Probabilities are given a value between 0 (0% chance or will not happen) and 1 (100% chance or will happen). You cannot have a negative percent for something that will not happen or a percent greater than 100 for something that will happen.
How do you get Whitney on animal crossing wild world?
Just chance when you get a new resident.
If your sister is a twin what is your chance of having twins?
actually u have a greater chance of twins then
How do you swim in animals crossing?
Using Animal Crossing Wild World you can't. However, using action replay there is a chance you can. But (and it's a BIG but) you can swim normally on animal crossing 3DS, which is yet to be released.
What is the likelihood of inheriting a specific combination of alleles in an individual?
The likelihood of inheriting a specific combination of alleles in an individual is determined by the random assortment of alleles during meiosis, which is the process of cell division that produces gametes (sperm and egg cells). This means that the chance of inheriting a specific combination of alleles is 50 from each parent, resulting in a unique genetic makeup for each individual.
