Unformatted text preview: recombination across generations and it's required to increase the ability of a population
to survive. Dihybrid crosses: A cross that involves two genes, each consisting of heterozygous alleles.
Multiple traits are inherited at the same time. Law of independent assortment: If genes are located on separate chromosomes they will be inherited independently of one another. Freckles is a dominant trait (F) that is controlled by a single gene. If a person's genotype is
P}: The person would have freckles. RR - Red: RI - Pink; rr - White is an example of incomplete dominance In a codominant trait, with the genotype, the resulting phenotype would be; Both traits
are expressed fully (e.g., spotted). If these traits Dd x dd, were to be crossed, there would be a 50% chance that the offspring
would show their phenotypes. The human blood type is a codominant trait. where both A, and B are dominant. and blood
type 0 is recessive. Describe the genotypes, and phenotypes of the possible offspring of two people with
blood type AB (genotype: TA TB). Blood Types .._( 4—H T 50% gfi Dmsffl??? wm howeun #5 HOT) 'L‘Sfi’oofi 0M5?

afifioEE Genotype 8: Phenotype: Genotype is what information our genes give and it refers to the pairing of alleles.
Phenotype is the traits that we see in an organism and it has nothing to do with the info on the genes. For example, if we have "B" for blue eyes and “b" for green eyes, then there ...
