Gene: characteristic of an organism found on a chromosome
Allele: variation of a characteristic/ gene
Law of segregation: 2 alleles of a trait separate during meiosis
Law of independant assortment: chromosomes/ genes separate randomly during meiosis
genotype: genes present in an individual
phenotype: individuals observable traits
heterozygous: 2 alleles of a pair of alleles are different
homzygous: 2 alleles of a pair of alleles are the same
dominant allele: trait is always expressed when present
recessive allele: trait is only expressed when 2 copies are preesnt
co-dominance: two traits are dominant/expressed
incomplete dominance: one trait is partically dominant over another
se-linked inheritance: gene found on the X chromosome

There is an inherited syndrome in humans in which the cells cannot convert food into energy. Some of the symptoms include
muscle weakness and a lack of coordination. Which malfunctioning organelle within the cell can cause this condition?
A. centrioles
B. lysosomes
C. mitochondria
D. ribosomes
Answers
Answer:
It really depends what cells are affected but most times the mitochondria cells cause such symptoms to the human. According to the Mayo Clinic (to back up my answer) symptoms include, "poor growth, developmental delays, and muscle weakness." None of the other cells proved to have much of the same symptoms that affected the muscles which is why I think the mitochondria is the correct one.
