●● what is a sex chromosome
Answer: A chromosome that determines the sex of an individual.
●● what is a somatic cell?
Answer: Any cell of the body except sperm and egg cells (they are
diploid and we have 46)
●● What are gametes?
Answer: Reproductive cells (sperm and egg) that carry genetic
information.
●● What is a karyotype?
Answer: the number and visual appearance of the chromosomes in the
cell nuclei of an organism or species.
●● What is an allele?
Answer: Different forms of a gene that can exist at a specific locus.
, ●● What is a genotype?
Answer: genetic makeup of an individual
●● What is a phenotype?
Answer: The observable physical or biochemical characteristics of an
individual.
●● what is Mendel's laws of segregation?
Answer: the principle that alleles of homologous genes separate from
each other at meiosis
●● what is Mendel's laws of independent assortment?
Answer: The principle that alleles of different genes assort
independently of one another during gamete formation.
●● What is a dihybrid cross?
Answer: A genetic cross that follows the inheritance of two different
traits.
●● what is Non-disjunction?
Answer: The failure of homologous chromosomes or sister chromatids
to separate properly during cell division.
