TEST PAPER 2026 QUESTIONS AND
SOLUTIONS GRADED A+
●● Genetics.
Answer: the science that deals with the study of heredity and variation
●● Heredity.
Answer: the transmission of traits from one generation to the next
●● Variation.
Answer: similarities and differences
●● quantitative genetics.
Answer: study of measurable traits
●● population genetics.
Answer: study of traits in a group of individuals
●● cytogenetics.
Answer: study of chromosomes
,●● molecular genetics.
Answer: molecular function and structure of genes
●● Mendelian Genetics.
Answer: transmission of genes and traits from generation to generation
●● genome.
Answer: total genetic component of an organism
●● DNA.
Answer: genetic material of living organisms - mode of inheritance
●● chromosome.
Answer: contains the genetic material: DNA and RNA
●● chromatin.
Answer: it the chromosomal material in its decondensed, threadlike state
●● chromosome compliment.
Answer: the number of chromosomes in a species
,●● chromosomal theory of inheritance.
Answer: the two members of each pair of homologous pair of
chromosomes carry alleles for the same genes and therefor, affect the
same traits.
●● haploid.
Answer: one copy of each chromosome
●● Diploid.
Answer: two copies of each chromosome
●● autosome.
Answer: found in homologous pairs, chromosomes that are closely
matched in size and shape
●● sex chromosome.
Answer: those that determine the gender of the organism
●● p arm.
Answer: short arm
●● q arm.
Answer: long arm
, ●● Centromere.
Answer: the region of the chromosome that holds the two sister
chromatids together
●● telocentric.
Answer: centromere at end
●● acrocentric.
Answer: centromere close to end
●● submetacentric.
Answer: centromere slightly off center
●● metacentric.
Answer: centromere in middle
●● Phrophase.
Answer: First stage of mitosis. DNA breaks into visible chromosomes
and nuclear membrane breaks down. Centrioles move to opposite ends
of the cell.
●● metaphase.
