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.

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !

hydrogen is a compound or a single element and a element is a pure substence that cannot be separated into simpler subtances

clorine is a compound its a chemical substance that forms when two or more different elements combine

so both hydrogen and clorine are compounds
