Help the Rossis understand how it is that Kai has NF1. Did he acquire it from them, or, was his case spontaneous? Explain your reasoning and, in your explanation, include the following terms or concepts, underline each: genotype phenotype, hom0zygous heterozygous inheritance alleles dominant recessive

Respuesta :

Neurofibromatosis type 1, also know as NF1 is a genetic disorder that is caused by gene changes (also called mutations). The NF1 Gene is found on chromosome 17 and it carries the instructions to create a protein called NF! NF1 regulates mitosis, and works to prevent cells from growing and dividing in an uncontrolled way. The cells of individuals with NF1 divide out of control, leading to the creation of tumor. We have found that Kai has one mutation that was detected in the NF1 gene.

Kai may have NF1 Because of the parents may be a carrier The genes we inherit compose our genotype and determine the physical characteristics we possess, our phenotype. Alleles are important for the variations in which the trait can be expressed. The stronger allele is known as the dominant gene, and the weaker allele is known as the recessive gene. A phenotype is an individual's observable traits, such as height, eye color, and blood type.

The genetic contribution to the phenotype is called the genotype. The gene changes can be passed from parent to child, or they can happen on their own. If you have NF1 or NF2, your baby has a 50-percent chance (1 in 2) of inheriting it from you. heterozygous are carriers in recessive genetic disorders a person with recessive alleles but does not display trait, can pass the trait.

When there is two identical alleles of a particular gene that is h.o.m.ozygous and if there is two different alleles of a particular gene or genes, then that is heterozygous.

Neurofibromatosis kind 1, additionally recognise as NF1 is a genetic disease this is due to gene adjustments (additionally referred to as mutations).

  1. The NF1 gene is discovered on chromosome 17 and it includes the commands to create a protein referred to as  NF1 regulates mitosis, and works to save you cells from developing and dividing in an out of control way.
  2. The cells of people with NF1 divide out of control, main to the advent of tumor. We have discovered that Kai has one mutation that changed into detected withinside the NF1 gene.
  3. Kai can also additionally have NF1 Because of the mother and father can be a provider the genes we inherit compose our genotype and decide the bodily traits we possess, our phenotype.

What is genetic contribution?

The genetic contribution to the phenotype is referred to as the genotype. The gene adjustments may be exceeded from determine to child, or they could occur on their own.

Thus it is clear.
