Answer:

Pedigree analysis

Explanation:

Pedigree analysis is a type of research used to study gene inheritance in humans. It is used to interpret genetic information or trait patterns displayed in a family tree. Pedigree analysis tries to analyze and determine the absence or the presence of a trait in relation to family members.

When a pedigree is done it  shows the family history of a trait, hence can reveal, what chromosome the trait is linked to, family genotypes, dominant or recessive traits and phenotype probabilities in unborn children.

Therefore, from the question, the investigator is doing a type of hereditary research called pedigree analysis.

Vaselesa [24]

The probability of producing a transgender = None ( D ) when the father is gay

The probability of producing male gamete is not affected by the sexual orientation of the Father because the production of the male gamete is carried by the spermatogonia found in the testes of a male. and every male specie regardless of your sexual orientation have testicles where the spermatogonia undergoes mitotic divisions to produce the male gametes.

Homzygous means two identical alleles so a and c are both homzygous

recessive genes are not expressed if a dominant allele is present but with be expressed if the no dominant allele is present.

If you do a cross test you can determine the percentage.

Hagatha is heterozygous meaning non identical allele like Dd or dD and the other is homzygous recessive meaning that it has identical allele like DD or dd but it's recessive so it's dd.
