To answer your questions, let’s assume you are referring to a genetic cross involving two traits, with “E” representing the allele for three eyes (dominant) and “e” representing the allele for two eyes (recessive).
1. What percentage of offspring would have 3 eyes? – 75% (assuming the cross is between Ee x Ee, where E is dominant for three eyes)
2. What percentage of offspring would have 2 eyes? – 25% (these would be the homozygous recessive ee offspring)
3. The ratio for offspring with three eyes is – 3:1 (in a typical Mendelian cross of Ee x Ee, you get 3 genotypes with E and 1 with ee)
4. The ratio for offspring with two eyes is – 1:3 (1 portion for two eyes out of the total four)
5. Three eyes is the – dominant trait.
6. Two eyes is the – recessive trait.
This information stems from typical Mendelian genetics where dominant traits mask recessive ones in offspring. If you’d like further details or examples, feel free to ask!
