2025/2026 Exam Questions with 100%
Correct Answers | Latest Update
Cellular Genetics - 🧠ANSWER ✔✔pertains to the cellular organization of
genetic materials, i.e., chromatin materials
Molecular Genetics - 🧠ANSWER ✔✔based on the biochemistry of genes
and the structures that support genes, i.e., DNA, and various proteins that
are part of the chromosomal architecture
Gene - 🧠ANSWER ✔✔Section of DNA along chromosome
- italicized when describing a genetic inheritance pattern ( A, B, and O
gene)
Alleles - 🧠ANSWER ✔✔One of two or more different genes that may
occupy a specific locus on a chromosome. "An alternate form of gene"
Locus - 🧠ANSWER ✔✔Specific location of a gene on a chromosome

1
,Amorph - 🧠ANSWER ✔✔A silent gene; a gene that does not appear to
produce a detectable antigen, such as Jk, Lu, O
Genotype - 🧠ANSWER ✔✔Sequence of DNA that is inherited; an
individual's actual genetic makeup
Phenotype - 🧠ANSWER ✔✔Produced by the genotype, including an
enzyme to control a blood group antigen; and then length of long bones of
the skeleton
- *the physical or observable expression of a genotype*
; they are not italicized when describing an inheritance pattern
Dominant Gene - 🧠ANSWER ✔✔a trait or characteristic that will be
expressed in the offspring even though it is only carried on one of the
homologous chromosomes
Recessive Gene - 🧠ANSWER ✔✔a type of gene that, in the presence of its
dominant allele, *does not express itself*
Co-dominant Gene - 🧠ANSWER ✔✔a pair of genes in which neither is
dominant over the other; that is they are both expressed

, Homozygous - 🧠ANSWER ✔✔presence of two identical alleles on both
chromosomes
- EX: AA or BB
Heterozygous - 🧠ANSWER ✔✔Inheritance of different allele from each
parent at a particular locus
- EX: AO or AB
Autosomal - 🧠ANSWER ✔✔Traits not carried on the sex chromosome
Autosomal dominant - 🧠ANSWER ✔✔Traits physically expressed by all
members of the family that carry the allele
Prokaryotic - 🧠ANSWER ✔✔Without a defined nucleus
Eukaryotic - 🧠ANSWER ✔✔With a define nucleus (human beings and all
other mammals
Histones - 🧠ANSWER ✔✔Long polymers of DNA and basic proteins that
*comprises the chromatin to keep chromosome shape.*
- highly basic protein of which DNA is coiled around
