Inheritance and monohybrid

• Allele is different versions of the same genre which can be either dominant or recessive. Each human can only inherit 2 alleles for each gene. An examples is blood type such as A and B (dominant) as well as O (recessive).
• Punnett Square is used to predict the possible gene makeup of offspring.
• Both pairs of a gene are the same for a particular trait– is called homozygous or purebred.
• One dominant and one recessive gene for a particular trait – called heterozygous or hybrid.
• A gene is a segment of DNA that determines a trait.
• Humans have 46 chromosomes or 23 pairs, one set from dad and one set from mum.
• Gregor Mendel is known as the Father of Genetics.
• Incomplete dominance occurs when one allele is not completely dominant over another, causing the alleles to blend.
• Codominance occurs when both alleles are expressed.
