angela has a black heterozygous male cat and a white female cat black is dominant and white is recessive what are the genotypic ratios of this cross

See below

Explanation:

Since the coat color black is a dominant trait, it can be represented by capital B. White colored coat for the female cat is a recessive trait so we can represent it with a small case b.

male parent: Bb x female parent: bb

The genotypes of F1 as Bb:bb will come out in a 1:1 ratio. This means there is a 0.5 probability of each kitten from this litter to have a white or black coat color.

the overall balanced equation

6co2 + 6h2o > c6h12o6 + 6o2

sunlight energy

where: co2 = carbon dioxide

h2o = water

light energy is required

c6h12o6 = glucose

o2 = oxygen
