What does contig mean?
A contig–from the word “contiguous”–is a series of overlapping DNA sequences used to make a physical map that reconstructs the original DNA sequence of a chromosome or a region of a chromosome.
What is the recessive allele?
Recessive refers to a type of allele which will not be manifested in an individual unless both of the individual’s copies of that gene have that particular genotype.
What does heterogeneous mean in genetics?
Genetic heterogeneity can be defined as mutations at two or more genetic loci that produce the same or similar phenotypes (either biochemical or clinical).
What is a dominant allele simple definition?
Definitions of dominant allele. an allele that produces the same phenotype whether its paired allele is identical or different. synonyms: dominant.
How long is a contig?
Contig building reduced the total number of nucleotides used for further analysis from 4.13 million to 2.49 million and increased the length of the longest sequence from 979 to 1501 nucleotides.
What is a recessive allele example?
Recessive alleles only show their effect if the individual has two copies of the allele (also known as being homozygous?). For example, the allele for blue eyes is recessive, therefore to have blue eyes you need to have two copies of the ‘blue eye’ allele.
What is recessive and dominant allele?
Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.
What is heterogeneous disease?
A heterogeneous medical condition or heterogeneous disease is a medical term referring to a medical condition with several etiologies (root causes), such as hepatitis or diabetes.
What is a dominant allele example?
Dominant alleles show their effect even if the individual only has one copy of the allele (also known as being heterozygous?). For example, the allele for brown eyes is dominant, therefore you only need one copy of the ‘brown eye’ allele to have brown eyes (although, with two copies you will still have brown eyes).
What is a dominant allele Class 10?
– Dominant refers to the relationship between two versions of a gene. If the alleles (two versions of each gene) of a gene are different, one allele will be expressed as Dominant gene while the other allele effect is called recessive. For example- Baldness, Curly hair is dominant over straight hair etc.
What is the meaning of the word allele?
If the alleles are different, the individual is heterozygous. Though the term allele was originally used to describe variation among genes, it now also refers to variation among non-coding DNA sequences. “Allele” is the word that we use to describe the alternative form or versions of a gene.
What does contig stand for in DNA sequencing?
Contig can also refer to the overlapping clones that form a physical map of a chromosome when the top-down or hierarchical sequencing strategy is used. In this sequencing method, a low-resolution map is made prior to sequencing in order to provide a framework to guide the later assembly of the sequence reads of the genome.
Which is the best definition of a contig?
con·tig map. a physical map of a chromosome or stretch of DNA constructed from sets of overlapping clones (contigs).
Which is an example of an archaic allele?
— Quanta Magazine, 14 Sep. 2017 For example, some of the archaic alleles Sankararaman spotted in Africans were in genes that suppress tumors and regulate hormones.
