To determine which of the given options is an example of codominance, we first need to understand the concept of codominance in genetics.1. Understanding Codominance: Codominance occurs when both alleles in a heterozygous genot

The phenotype of yotari is very similar to that of reeler. yotari mutants are recognizable by their unstable gait and tremor and by their early deaths at around the time of weaning. The cerebella of homozygous yotari are hypoplastic and have no foliation. A molecular and a granular cell ...

Moreover, genetic crosses of homozygous mutants of this new mutant allele with the previously isolated mutants rth1 to rth5 resulted in complementation thus demonstrating that these mutants are not allelic. Therefore, this new mutant was designated roothairless6 (rth6). Subsequently, additional rth6...
Which allele is expressed in the dominant homozygous, heterozygous and homozygous recessive genotypes?Homozygous vs. Heterozygous Genotypes:The term genotype refers to the different alleles, or variations, that an organism has for a specific gene. A homozygous organism has ...
