Frequent question: What is the difference between a gene and an allele select the best answer quizlet?

What is the difference between a gene and an allele select the best answer?

So, what it is the difference between a gene and an allele? The short answer is that an allele is a variant form of a gene. Explained in greater detail, each gene resides at a specific locus (location on a chromosome) in two copies, one copy of the gene inherited from each parent.

What is the difference between an allele and a gene?

These gene variants still code for the same trait (i.e. hair color), but they differ in how the trait is expressed (i.e. brown vs blonde hair). 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.

What is the difference between a gene and an allele 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.

What information can be obtained by working a Punnett square quizlet?

A Punnett square helps you to determine the possible percentages of different genotypes in the offspring of two parents. A Punnett square can show the probability of an offspring with a given genotype resulting from a cross ,although, it cannot show actual offspring.

What allele means?

An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. … Alleles contribute to the organism’s phenotype, which is the outward appearance of the organism. Some alleles are dominant or recessive.

What is an allele example?

Alleles are different forms of the same gene. … An example of alleles for flower color in pea plants are the dominant purple allele, and the recessive white allele; for height they are the dominant tall allele and recessive short allele; for pea color, they are the dominant yellow allele and recessive green allele.

What is the difference between a gene and an allele chegg?

A gene is a segment of DNA that codes for a protein or RNA; the term allele refers to all of the DNA in a cell or organism.

What is the difference between an allele and a trait?

Traits are basically your phenotype. They include things like hair color, height, and eye color. Alleles are versions of genes. … For instance, in your hair gene, if you have the allele for brown hair, then you will have brown hair.

What are the differences and relationships between alleles genes and chromosomes?

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.

What is the difference between a locus and an allele?

The key difference between allele and locus is that the allele refers to one of the two or more alternative sequences of a gene at a certain locus while the locus refers to a certain location on a chromosome where a gene can be found.

What is the difference between a gene and DNA quizlet?

The difference between a DNA molecule and a gene

A DNA is a whole helical molecule made up of nucleotides arranged so that the order of the bases carry the inherited code for many genes whereas one gene is a short length of that DNA molecule and it codes for one inherited characteristic.

What is the difference between a dominant allele and a recessive allele?

When an allele is dominant, the characteristic it is connected to will be expressed in an individual. When an allele is recessive, the characteristic it is connected to is less likely to be expressed. Recessive traits only manifest when both alleles are recessive in an individual.

What does a Punnett Square Show Quizizz?

What is a punnett square? a graph used to predict the possible birth rate of offspring.

Which is dominant allele A or B?

With eye color, for instance, “B” stands for a brown allele and “b” stands for a blue allele. An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. Using the eye color example, this genotype is written BB.

When using a Punnett square where would you place the alleles of the parents?

A Punnett square is a tool used to predict the ratio or percentage of the possible genes that an offspring will have based on the genes of the parent. In a Punnett square, the top of the table shows the alleles provided by one parent. The alleles for the other parent are placed along the left side of the table.
