A genotype can be heterozygous or homozygous. Homozygous indicates that the gene contains two copies of the same allele. You are going to do a monohybrid cross between two flowers. One flower is white, the other flower is red. What is the genotype of the white flower? Quiz notes: Capital letters indicate dominance and lower case letters indicate recessive alleles. Alleles will be indicated by R and r. Red is the dominant flower color White is the recessive flower color

rr white flower

Explanation:

RR represent Red flower (homozygous dominant)

rr represents white flower (homozygous recessive)

Homozygous means the allele of the genotype is the same

Heterozygous means the allele of the genotype are different

A recessive trait-is a traits that doesn't express itself and its effect is mask by the effect of a dominant allele.

A dominant trait expresses itself in the phenotype of the individual.

rr is homozygous recessive whose phenotype is white flower.

burning of wood and coal

explanation:

the panel also concluded there's a better than 95 percent probability that human-produced greenhouse gases such as carbon dioxide, methane and nitrous oxide have caused much of the observed increase in earth's temperatures over the past 50 years.
