Is ALS dominant or recessive?
Yes, ALS (Amyotropic Lateral Sclerosis) is a genetic disorder. It affects the nerve cells involved in voluntary muscle movements. Mutation in a gene that produces enzymes for neuteralisation of free radicals; causes this disease. The free radicals damage the motor neurons. Treatment for ALS has not been discovered yet.
How is the inheritance of traits controlled in organisms?
Inheritance of traits in organisms is controlled by genes, which are segments of DNA that code for specific traits. These genes are passed from parents to offspring through sexual reproduction. The combination of genes from both parents determines the traits that are expressed in the offspring.
What is the term applied when one gene interferes with the expression of another?
Transcriptional Activator or Transcriptional Repressor. They bind to the promoter region thereby blocking the gene product Regulator
What did mendel discover about the inheritance traits?
Mendel drew two conclusions. Mendel concluded that biological inheritance is determined by factors that are passed from one generation to the next. Mendel also concluded that the principle of dominance states that some alleles are dominant and others are recessive.
Why are some phycal traits more common than others?
Physical traits can be more common than others due to a variety of reasons, including natural selection, genetic variation, and environmental influences. Some traits may offer a survival advantage in certain environments, leading to their prevalence in a population. Additionally, traits with a strong genetic basis or that are determined by dominant alleles are more likely to be common.
Is six fingers a dominate trait?
Having six fingers is typically considered a polydactyly trait, which is a rare genetic variation. Whether a trait is dominant or recessive depends on the specific genetic mutation causing it. In polydactyly cases, the inheritance pattern can vary, with some being dominant and others being recessive.
What are the states that some alleles are dominant and others are recessive?
Mendel's law of inheritance.
Why are some pea plant short while others are tall?
The tall gene is dominant in pea plants and there is no inbetween. This made them an ideal for Gregor Mendel to study in his study of genetic inheritance.
What is the mode of inheritance of hydrocephalus?
The mode of inheritance of hydrocephalus can vary depending on its underlying cause. It can be inherited in an autosomal dominant, autosomal recessive, or X-linked manner, depending on the specific genetic factors involved. Some cases are linked to genetic syndromes, while others may arise sporadically without a clear hereditary pattern. Environmental factors and developmental issues can also contribute to the condition.
What is Mendelian genetics and what are the basic laws of inheritance?
Mendelian genetics is the study of how traits are inherited from one generation to the next based on the work of Gregor Mendel. The basic laws of inheritance according to Mendel are the law of segregation (alleles separate during gamete formation), the law of independent assortment (genes for different traits segregate independently), and the law of dominance (some alleles are dominant over others).
Is ALS dominant or recessive?
Yes, ALS (Amyotropic Lateral Sclerosis) is a genetic disorder. It affects the nerve cells involved in voluntary muscle movements. Mutation in a gene that produces enzymes for neuteralisation of free radicals; causes this disease. The free radicals damage the motor neurons. Treatment for ALS has not been discovered yet.
Mendel was able to conclude that traits are inherited from parents and that no particular traits are shown more than others in offspring?
Yes, Mendel's experiments with pea plants led him to discover the principles of inheritance, including the concepts of dominant and recessive traits. He observed that traits are passed down from parents to offspring in predictable patterns, and that some traits may be more prominent than others depending on their genetic makeup.
How do you inherit alleles?
You inherit alleles from your parents through the process of reproduction. Each parent contributes one allele for each gene, resulting in a pair of alleles for every gene in the offspring. The combination of these alleles determines traits, with some alleles being dominant and others recessive. This genetic inheritance follows Mendelian principles, where allele segregation and independent assortment play key roles.
Is chromosomal mutation dominant or recessive?
Chromosomal mutations can be either dominant or recessive, depending on the specific mutation and how it affects the expression of genes on the altered chromosome. Some chromosomal mutations can lead to a dominant phenotype if they result in the duplication or gain of genetic material, while others can lead to a recessive phenotype if they result in the loss or deletion of genetic material.
How is the inheritance of traits controlled in organisms?
Inheritance of traits in organisms is controlled by genes, which are segments of DNA that code for specific traits. These genes are passed from parents to offspring through sexual reproduction. The combination of genes from both parents determines the traits that are expressed in the offspring.
The discovery that traits have dominant and recessive varieties of is contributed to?
The discovery that traits have dominant and recessive varieties is primarily attributed to Gregor Mendel, who conducted experiments with pea plants in the mid-19th century. His work established the foundational principles of inheritance, demonstrating how certain traits can mask others in offspring. Mendel's laws of segregation and independent assortment explained how traits are passed from parents to offspring, laying the groundwork for modern genetics. His findings revealed the predictable patterns of heredity, which are crucial for understanding genetic variation.
Is pku sex linked recessive or sex dominant?
I think I read somewhere that there are some variants of it that are recessive and others that are dominant.
