  • What is the dominant allele over the recessive allele?

    The dominant allele is the allele that is expressed when an individual has one copy of that allele. It masks the expression of the recessive allele when present. In genetic terms, the dominant allele is represented by a capital letter, while the recessive allele is represented by a lowercase letter. When an individual has two copies of the dominant allele or one copy of the dominant allele and one copy of the recessive allele, the dominant trait will be expressed.

  • What is the difference between gene pool and allele frequency or allele frequency?

    The gene pool refers to the total collection of genes in a population, including all the different alleles for each gene. Allele frequency, on the other hand, refers to the proportion of a specific allele in a population's gene pool. In other words, allele frequency is a measure of how common a particular version of a gene is within a population. Therefore, while the gene pool encompasses all the genetic variation in a population, allele frequency specifically focuses on the frequency of individual alleles within that gene pool.

  • What is a dominant recessive allele?

    A dominant allele is a genetic variant that is expressed when present in a single copy in an individual's genotype. It masks the expression of the corresponding recessive allele. On the other hand, a recessive allele is only expressed when an individual has two copies of it in their genotype. In a heterozygous individual (having one dominant and one recessive allele), the dominant allele will be expressed, while the recessive allele will be masked. This is the basis of Mendelian genetics and inheritance patterns.

  • How do you calculate allele frequency?

    Allele frequency is calculated by counting the number of times a specific allele appears in a population and dividing it by the total number of alleles for that gene in the population. This can be represented as a fraction or a percentage. For example, if there are 200 individuals in a population and 300 alleles of a specific gene, and 100 of those alleles are the "A" allele, the frequency of the "A" allele would be 100/300 = 0.33 or 33%.

  • What does the term "sick allele" mean?

    The term "sick allele" refers to a specific variant of a gene that is associated with a disease or disorder. This allele may result in a malfunctioning or non-functioning protein, leading to the development of a particular illness. In genetic terms, a sick allele is considered a pathogenic or disease-causing variant. Understanding the presence of sick alleles can be crucial for diagnosing and treating genetic disorders.

  • What does the term allele designation mean?

    Allele designation refers to the specific label or symbol used to represent a particular version of a gene. Each allele designation is typically represented by a letter or combination of letters, such as A, B, or AB. These designations are used to distinguish between different variations of a gene that can produce different traits or characteristics. For example, in the ABO blood group system, the alleles for blood type are designated as A, B, and O.

  • What is the definition of an allele pair?

    An allele pair refers to the two forms of a gene that an individual inherits from their parents. Each allele in the pair can be the same (homozygous) or different (heterozygous), and they determine the specific trait or characteristic that is expressed in an organism. Allele pairs are important in genetics as they influence the phenotype, or physical appearance, of an individual.

  • What is the difference between gene and allele?

    Genes are segments of DNA that determine specific traits or characteristics in an organism, while alleles are different forms of a gene that can produce variations in those traits. Genes are the basic unit of heredity, while alleles are specific versions of a gene that can be dominant or recessive. For example, the gene for eye color may have alleles for blue, brown, or green eyes.

  • What is a gene and what is an allele?

    A gene is a segment of DNA that contains the instructions for making a specific protein or RNA molecule. Genes are the basic unit of heredity and are passed down from parents to offspring. An allele is a specific version of a gene, which can vary in sequence and can result in different traits or characteristics. For example, the gene for eye color may have different alleles that result in blue, brown, or green eyes.

  • What is the difference between allele frequency and gene pool?

    Allele frequency refers to the proportion of a specific allele in a population. It is a measure of how common a particular version of a gene is within a population. On the other hand, the gene pool refers to the total collection of genes in a population at a particular time. It includes all the different alleles for each gene present in the population. In other words, allele frequency is a specific measure of the gene pool, focusing on the frequency of individual alleles within the overall genetic diversity of a population.

  • What is the relationship between the allele traits homozygous and heterozygous?

    Homozygous and heterozygous are terms used to describe the genetic makeup of an individual for a particular trait. Homozygous individuals have two identical alleles for a specific gene (e.g., AA or aa), while heterozygous individuals have two different alleles (e.g., Aa). The relationship between the two is that homozygous individuals will express the trait determined by the dominant allele if present, while heterozygous individuals will exhibit the dominant trait due to the presence of one dominant allele.

  • What is the relationship between the allele characteristics of homozygous and heterozygous?

    Homozygous individuals have two identical alleles for a particular gene, while heterozygous individuals have two different alleles. This difference in allele characteristics can result in different phenotypic expressions. In some cases, one allele may be dominant over the other, leading to a dominant phenotype in heterozygous individuals. In contrast, recessive alleles may only be expressed in homozygous individuals.
