   The dominant/recessive character is a relationship between two alleles and must be determined by observation of the heterozygous phenotype. An example of a simple phenotype is the flower colour in Mendel’s peas. One allele as a homozygote produces purple flowers, while the other allele as a homozygote produces white flowers.

   Oct 12, 2024 · dominance, in genetics, greater influence by one of a pair of genes (alleles) that affect the same inherited character. If an individual pea plant with the alleles T and t (T = tallness, t = shortness) is the same height as a TT individual, the T allele (and the trait of tallness) is said to be completely dominant.

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

   • The dominant allele is capitalized and the recessive allele is lower case. The letter used for the gene (seed color in this case) is usually related to the dominant trait (yellow allele, in this case, or “ Y ”). Mendel’s parental pea plants always bred true because both produced gametes carried the same allele.

   Which contrasting allele is dominant and recessive?

   • In all seven pea-plant characteristics, one of the two contrasting alleles was dominant, and the other was recessive. Mendel called the dominant allele the expressed unit factor; the recessive allele was referred to as the latent unit factor.

   How many copies does a gene need to express a dominant phenotype?

   • In a diploid organism, if an allele is dominant, only one copy of that allele is necessary to express the dominant phenotype. If an allele is recessive, then the gene needs to have two copies (or be homozygous) to express the recessive phenotype.

   How do homozygous dominant and recessive genes differ?

   • For a gene that is expressed in a dominant and recessive pattern, homozygous dominant and heterozygous organisms will look identical (that is, they will have different genotypes but the same phenotype), and the recessive allele will only be observed in homozygous recessive individuals (Table 6.2.1 6.2. 1).

   What is an example of a dominant phenotype?

   • For example, when crossing true-breeding violet-flowered plants with true-breeding white-flowered plants, all of the offspring were violet-flowered, even though they all had one allele for violet and one allele for white. Rather than both alleles contributing to a phenotype, the dominant allele will be expressed exclusively.

   Sep 17, 2023 · The recessive trait will only be expressed by offspring that have two copies of this allele (Figure 6.2.2 6.2. 2), and these offspring will breed true when self-crossed. Figure 6.2.2 6.2. 2: The allele for albinism, expressed here in humans, is recessive. Both of this child’s parents carried the recessive allele.
