Which mendelian idea is depicted by a cross in which the F1generation ...
Co-dominance
Co-dominance is the mendelian idea depicted by a cross in which the F1 generation resembles both parents. This phenomenon occurs when both alleles in a heterozygous individual are fully expressed, resulting in a phenotype that shows characteristics of both alleles.
Explanation:
- In co-dominance, neither allele is dominant or recessive, and both are expressed in the heterozygous condition.
- This leads to the offspring displaying a phenotype that is a combination of the phenotypes of the parents.
- For example, in a cross between a red flower (RR) and a white flower (WW), the offspring with the genotype RW will have petals that are both red and white, showing co-dominance.
Significance:
- Co-dominance allows for a greater diversity of phenotypes within a population.
- It also highlights the complexity and variation that can arise from the interaction of multiple alleles.
In conclusion, when the F1 generation resembles both parents, it indicates co-dominance, where both alleles are fully expressed without dominance.
