How do new phenotypes appear in a population
WebApr 28, 2024 · A dominant trait is an inherited characteristic that appears in an offspring if it is contributed from a parent through a dominant allele. Traits, also known as phenotypes, may include features such as eye color, hair color, immunity or susceptibility to certain diseases and facial features such as dimples and freckles. 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.
