What is considered a purebred? [Expert Review!]

WebWhen 2 parents breed, they each have a genotype, let's say one is AA, the other is aa. Both are purebred and homozygous. In its offspring, they create a new genotype, one letter from each of the parent's genotype. This creates many outcomes, including the heterozygous, Aa. WebGenotype determines phenotype, an organism's observable features. When an organism has two copies of the same allele (say, YYor yy), it is said to be homozygousfor that gene. If, instead, it has two different copies (like Yy), we can say it is heterozygous. WebBecause each possibility is equally likely, genotypic ratios can be determined from a Punnett square. If the pattern of inheritance (dominant and recessive) is known, the phenotypic ratios can be inferred as well. For a monohybrid cross of two true-breeding parents, each parent contributes one type of allele. design by natalia

Co-dominance and Incomplete Dominance (video) Khan Academy

WebIncomplete dominance can occur because neither of the two alleles is fully dominant over the other, or because the dominant allele does not fully dominate the recessive allele. Co-dominance can occur because both the alleles of a gene are dominant, and the traits are equally expressed. ( 2 votes) WebAny organism that is homozygous for multiple traits is a purebred.
