what is the difference between an allele and a gene (locus) quizlet?

A gene is a specific section of a chromosome where the base pairs that code for the characteristic are stored whereas an allele is the actual sequence of the base pairs in the section.

Gene is a functional piece of DNA for a specific trait while alleles are a different variation of a gene. ... The genes are present in all known organism while not all the alleles are present in all the organism. Genes govern a trait or a group of traits while the alleles produce different phenotypes for different traits.

When genes mutate, they can take on multiple forms, with each form differing slightly in the sequence of their base DNA. ... Different versions of the same gene are called alleles. Genes can have two or more possible alleles. Individual humans have two alleles, or versions, of every gene.

In multiple alleles the same strand of DNA is involved. For example the blood type is found on the same strand of DNA. ... The polygenic inheritance is found on multiple strands of DNA. For example the formation of antibiotics to fight bacteria and other foreign bodies are found on multiple places on the DNA.

Alleles are different forms of same gene. Genes are linearly arranged on chromosomes. Chromosomes contain genetic material of cell i.e. DNA. So chemically alleles, genes, chromosomes are all DNA !

Alleles in the parent cell are genetically-similar to the alleles in the daughter cells in mitosis while the alleles in the parent cell are genetically-different from the alleles in the daughter cells in meiosis. Thus, this is the main difference in alleles between parent cell and daughter cells.

A recessive gene is a gene whose effects are masked in the presence of a dominant gene. Every organism that has DNA packed into chromosomes has two alleles, or forms of a gene, for each gene: one inherited from their mother, and one inherited from their father.

The Brainliest Answer! Genes are the unit of dna which is present on chromosome while chromosomes are long thread like structure which contains genetic material on it present in nucleus.

heterozygous. Genes come in pairs, called alleles, and each pair is located in a specific position (or locus) on a chromosome. If the two alleles at a locus are identical to each other, they are homozygous; if they are different from one another, they are heterozygous.

Allele frequency refers to how common an allele is in a population. It is determined by counting how many times the allele appears in the population then dividing by the total number of copies of the gene. The gene pool of a population consists of all the copies of all the genes in that population.

Except in some viruses, genes are made up of DNA, a complex molecule that codes genetic information for the transmission of inherited traits. Alleles are also genetic sequences, and they too code for the transmission of traits. ... The short answer is that an allele is a variant form of a gene.

Genes and Chromosomes. Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes.

Gene. A gene is a stretch of DNA or RNA that determines a certain trait. Genes mutate and can take two or more alternative forms; an allele is one of these forms of a gene. ... Chromosomes occur in pairs so organisms have two alleles for each gene — one allele in each chromosome in the pair.

An allele is an alternative shape of a gene (one member of a pair) this is placed at a particular function on a specific chromosome... Gametes are reproductive cells (sex cells) that unite at some point of sexual reproduction to shape a new mobile called a zygote.

Mutations Are Recessive or Dominant Different forms of a gene (e.g., normal and mutant) are referred to as alleles. Since diploid organisms carry two copies of each gene, they may carry identical alleles, that is, be homozygous for a gene, or carry different alleles, that is, be heterozygous for a gene.

A gene is a section of DNA located at a particular site on a DNA molecule, called its locus. The base sequence of each gene carries the coded genetic information that determines the sequence of amino acids during protein synthesis.

The main difference in alleles between parent cell and daughter cells is that in mitosis, alleles of parent cell and daughter cells are genetically identical whereas, in meiosis, they are genetically different. That means; genetic recombination occurs through chromosomal crossing-over during meiosis.
