Bio Review

Polygenic - A trait is influenced by more than one allele, such as skin color and height, which results in a wide range of possibilities

Karyotype - diagram used to map out the 46 chromosomes that humans have (22 somatic 2 gametes)

Karyotype

Chromosomal Inheritance - The main principle that genes are physically located on chromosomes and are then divided by meiosis into individuals to create certain characteristics

Human Chromosomal Variation - Includes certain accidents in chromosomes, such as down syndrome where there’s an extra chromosome, and other certain chromosomal entities

Sex-linked genes - X/Y chromosomes

Law of Segregation - Mendel genetic law that says alleles separate during gamete formation

Chi-Square Analysis

  • Null Hypothesis - Any difference between the observed and expected data is due to chance

THINGS TO LOWKEY REMEMBER

Sex linked recessive traits - BOTH parents must have it; offspring if female must be homozygous
