NEST2024BiologyPrinciples of Inheritance and Variation
In a given plant, the flower colour is governed by a single gene locus. The flower can be either white, red, blue or purple colour. However, a single flower will never have different coloured petals. Multiple crosses were carried out between plants with different flower colours (white, red, blue or purple) and the observations on the progeny phenotype are tabulated. array |l|l| cross & progeny phenotypes White X Whit
Options
- AThere are two alleles governing flower colour.
- BPurple allele is dominant over Red allele, and Red allele is dominant over Blue allele.
- CRed allele and Blue allele show incomplete dominance.
- DWhite allele is dominant over purple allele.
Correct answer
C. Red allele and Blue allele show incomplete dominance.
