Quiz zum Vortrag
A monster's horns are either blue or red and rough or smooth. Blue and rough are dominant traits. Two heterozygous monsters with blue and rough horns mate. If their breeding follows Mendelian genetics, what phenotypic ratio types are expected?
- 9 blue and rough : 3 blue and smooth : 3 red and rough : 1 red and smooth
- 9 blue and smooth : 3 blue and rough : 3 red and rough : 1 red and smooth
- 9 blue and rough : 3 blue and smooth : 3 red and smooth : 1 red and rough
- 9 red and rough : 3 blue and smooth : 3 blue and rough : 1 red and smooth
- 9 red and smooth : 3 blue and smooth : 3 red and rough : 1 blue and rough
Which of the following is a conclusion Mendel made from his dihybrid crosses?
- Traits and their alternate forms segregate independently from other traits and their alternate forms in gamete formation.
- All dominant traits segregate together in gamete formation.
- All recessive traits segregate together in gamete formation.
- All traits segregate with traits from the same parent line.
- When heterozygous forms of a trait come together, they always form a blended phenotype.
