Apa perbedaan genotipe dan fenotipe?
Genotype is the genetic makeup; phenotype is the observable trait.
Genotype is the observable trait; phenotype is the DNA sequence.
Genotype is influenced only by the environment; phenotype is fixed.
Genotype and phenotype are identical terms.
Apa yang dimaksud dengan hukum pemisahan (Law of Segregation)?
Alleles separate independently from different chromosomes.
Allele pairs separate during gamete formation.
Genes always stay linked during meiosis.
Dominant alleles always mask recessive alleles.
Mengapa sifat terkait seks memiliki pola pewarisan yang berbeda?
Because sex-linked genes mutate more often.
Because they are located on autosomes.
Because sex chromosomes are inherited differently from autosomes.
Because only males inherit sex chromosomes.
Apa yang dimaksud dengan epistasis
A single gene affecting multiple traits.
One gene masking or altering another gene's expression.
Two alleles expressing equally in a heterozygote.
A mutation causing gene silencing.
Apa yang dimaksud dengan mutasi missense?
A mutation that does not change the amino acid sequence.
A mutation that changes a codon, resulting in a different amino acid.
A mutation that changes a codon into a stop signal.
A mutation that deletes an entire chromosome.
Mengapa crossing-over penting dalam proses meiosis?
It prevents chromosome breakage.
It produces new allele combinations increasing genetic variation.
It ensures identical daughter cells.
It maintains chromosome number.
Apa yang dimaksud dengan alel kodominan?
Alleles that mask each other completely.
Alleles expressed alternately in different tissues.
Alleles that are both fully expressed in a heterozygote.
Alleles expressed only in homozygous individuals.
Mengapa pewarisan mitokondria bersifat maternal?
Because sperm mitochondria are always active.
Because only the oocyte contributes mitochondria to the zygote.
Because mitochondria replicate only in males.
Because mitochondrial DNA is nuclear-like.
Apa perbedaan utama DNA genomik dan DNA mitokondria?
Genomic DNA is circular; mitochondrial DNA is linear.
Genomic DNA is nuclear; mitochondrial DNA is located in mitochondria.
Both have identical gene content.
Mitochondrial DNA contains all genes for cell growth.
Mengapa mutasi pada sel germinal lebih berpengaruh terhadap evolusi?
Because germline mutations cannot be inherited.
Because somatic mutations are more stable.
Because germline mutations are heritable.
Because somatic mutations spread faster in populations.
