3. a pedigree can be used to
a. determine whether a trait is inherited.
b. show how a trait is passed from one generation to the next.
c. determine whether an allele is dominant or recessive
d. all of the above

4. blood typing is an example of this is where there is one gene but that one gene can have several different characteristics
a. multiple alleles
b. dihybrid trait
c. homozygous dominance
d. incomplete dominance

A chart illustrating the hereditary pattern of a family and its generation is called a pedigree chart. It represents the characters and illness of a family.

The correct option is Option D. All of the above

The correct answer for the blank is Option A. Multiple alleles

The correct answer is Option B. Recessive

The correct answer is Option B. The products of cellular respiration are the reactants of photosynthesis.

The correct option is Option C. Autosomal dominant

The correct answer is Option A. The closer the light source the higher will be the amount of oxygen.

Explanation:

3. A pedigree is a family tree that maps how a trait appears in a family.It maps the inheritance of the trait from generation to generation, and shows scientists features of the trait, for example the pattern of inheritance, whether it is sex linked, and  whether it is dominant or recessive

4. There are multiple alleles that cause different blood type phenotypes in humans, but these are all variations of one gene. There are A, B, and O alleles. A and B show codominance, if a person has both of these alleles they will express both as part of the phenotype.

10. The trait is recessive. This can be definitively determined because there are individuals in the youngest generation who have the trait even though neither of their parents have it. This means both parents must be heterozygous for the trait

Respiration question . b. The reactants of photosynthesis are carbon dioxide and water, which, with sunlight, are used to make sugars, which can be used as an energy source for the cell, and oxygen as a by-product. The glucose and oxygen are used in cellular respiration to produce chemical energy, with the release of carbon dioxide and water.

4. The inheritance cannot be sex-linked, because there is an affected male in generation II who must have got his Y chromosome from his affected dad (and therefore his X from his unaffected mother). This is likely autosomal dominant, because all the affected individuals go on to have affected children.

9. The chart shows that the closer the plant is to the light source, the more gas is produced. This gas is oxygen, which is released during photosynthesis. Therefore, the closer the light source, the more chemical energy available to drive photosynthesis and the more photosynthesis that is carried out
