In certain flowers, blue and yellow flowers are incompletely dominant to each
other. Show the cross between a pure blue flower and a pure yellow flower
The cross between a pure blue flower and a pure yellow flower is attached as an image. The genotypes of the parents are as follows:
Pure blue flower = BBPure yellow flower = YYWhat is incomplete dominance?Incomplete dominance is a type of non-mendelian inheritance in which the alleles of a gene are neither dominant nor recessive over one another, hence, an intermediate phenotype is produced.
According to this question, blue and yellow flowers are incompletely dominant to each other in certain flowers.
The genotype of pure blue flower = BBThe genotype of pure yellow flower = YYA cross between BB × YY will produce an intermediate phenotype different from both parents.

Peat is a mixture of partially decomposed plant and animal material found in waterlogged, acidic, anaerobic environments. people debate whether peat is a fossil
fuel. to be considered a fossil fuel, a material must be of biologic origin, be used as a source of energy, and replenish on a time scale greater than human
lifetimes. peat reserves have declined over time. however, peat harvesters claim that a restoration process
can make peat a renewable resource and allow it to
be classified as a biofuel. the restoration process is outlined in the table.
