Phenotypes of offspring
WebThe offspring are formed when that gamete unites with one from another parent and the two copies of each gene (and chromosome) are restored. For cases in which a single gene controls a single characteristic, a diploid organism has two genetic copies that may or may not encode the same version of that characteristic.

WebJan 24, 2024 · The unknown genotype can be identified by analyzing the resulting phenotypes in the offspring. The predicted ratios observed in the offspring can be determined by using a Punnett square.

RR=Red, Rr=Pink, and rr=white Co-dominance: Both alleles contribute to the phenotype. Offspring will have combination of two alleles. E.g. RR=Red hair, Rr=Roan (mix of red and white hairs-almost looks pink), and rr=white Sex-linked trait: Genes located on the sex-chromosomes called sex-linked genes. Usually ...
