If shaded symbols indicate having a dominant trait, what must be the genotype of the father in this pedigree chart?

Heterozygous

Explanation:

The offspring both carry recessive genes. The recessive gene will show up more often if one of the parents are heterozygous of the gene along with the other having recessive.

If the father was had both of the dominant traits, the offspring would inherit his trait instead.

in 1972 the fluid—mosaic membrane model of membrane structure was proposed based on thermodynamic principals of organization of membrane lipids and proteins and available evidence of asymmetry and lateral mobility within the membrane matrix [s. j. singer and g. l. nicolson, science 175 (1972) 720–731].

the eggs of the insects should be the first thing collected at the scene.
