What is the difference between gene and genotype? What is an allele? What are the differences between dominant and recessive alleles? What are some examples of each allele as well? Explain the difference between
WHEN I was growing up, the explanation of dominant-vs.-recessive inheritance was always something along these lines: “A dominant trait is one that has its effect on you if you inherit it from either of your parents, whereas a recessive trait is one that affects you only if you inherit ...
A recessive trait definition is one that is only expressed when an organism has two recessive alleles for that trait. A trait is an observable characteristic. This includes things like hair color, blood type, and behaviors. A dominant trait will be expressed with one or two dominant alleles...
Explain the difference between a dominant gene and a recessive gene. 1. What type of gamete (for a given trait) is produced by a dominant homozygous individual? 2. What is the genotypical proportion of these gametes? 3. What about a recessive homozygous individual?
Dominant and Recessive are terms that primarily revolve around the realm of genetics, particularly in explaining how traits are inherited from parent to offspring. A dominant trait is one that becomes visible even if only one of the two inherited alleles (gene variants) supports that trait. This...
What is an autosomal dominant genotype? Genotype: The term "genotype" may be used in either of two ways. It may refer to the entire collection of genes of an organism, or it may refer to the two alleles inherited for a particular gene. ...
The X-linked gene XK that underlies McLeod neuroacanthocytosis was discovered in 1994. In 2001 and 2003, the genes CHAC and JPH3 involved in an autosomal-recessive and an autosomal-dominant type of neuroacanthocytosis were identified. Pantothenate kinase associated neurodegeneration can be seen as...
