Question

regarding variations of genetic dominance, determine to which category each scenario on the left belongs. then click and drag each to the appropriate category. labels drop zones reset all both parents must donate a blue - eyed allele for a 25% chance of expression in offspring. homozygous recessive for hypercholesterolemia results in childhood death. heterozygous results in young - adult death. homozygous dominant results in normal lifespan. types a and types b blood can both be passed on to offspring as type

Explanation:

1. When both parents must donate a blue - eyed allele for a 25% chance of expression in offspring, this is a recessive trait situation as recessive alleles require two copies (homozygous recessive) to be expressed.
2. For hypercholesterolemia, the different phenotypes based on homozygous recessive, heterozygous, and homozygous dominant genotypes show incomplete dominance as the heterozygous state has an intermediate phenotype between the two homozygous states.
3. Types A and B blood being passed on to offspring as Type AB shows codominance where both alleles are fully expressed in the heterozygous state.

Answer:

1. Both parents must donate a blue - eyed allele for a 25% chance of expression in offspring: Recessive
2. Homozygous recessive for hypercholesterolemia results in childhood death. Heterozygous results in young - adult death. Homozygous dominant results in normal lifespan: Incomplete Dominance
3. Types A and Types B blood can both be passed on to offspring as Type AB: Codominance
