If crossed two heterozygotes, dadb and dcdd, the proportion of genotype in the offspring would be 25% DaDc, 25% DaDd, 25% DbDc, 25% DbDd.
What is heterozygotes and what is genotype and how come the genotype proportion is such?
- Heterozygotes is the category of genotype having two traits in the character of the offspring.
- Genotype is the combination of genes coding for a particular character of an offspring in the organism.
- Heterozygous and homozygous are the two category of genotype that can be depicted through the traits.
- Homozygous trait have both the trait similar and heterozygous trait have both traits different present in the character.
- Here the question is asked of the genotype proportions that is expected in the offspring out of the given alleles.
- Hence the genotypic proportion would be 25% DaDc, 25% DaDd, 25% DbDc, 25% DbDd in the offspring after crossing two heterozygotes.
