Chapter 7-9 Learning Objectives

Front 1

I can explain how males and females can differ in sex-linked traits

Back 1

The X chromosome has many genes that affect many traits. In mammals females are XX and males are XY.

Females get the normal 2 alleles for a give trait, a male however only gets one allele, which is different from autosomal genes

C = color vision

c = Color blind

XCXc female carrier but normal vision

XcY male color blind

Front 2

I can predict the approximate ratios of genotype and phenotype of offspring from given parent traits and varying inheritance patterns

Back 2

Incomplete dominance - Heterozygous is a blend of the homozyous phenotypes

Red and White flower crossed RR x WW RW=pink

Codominance - heterozygous individual shows both traits fully.

IAIB has both the A and B blood antigens.

Multiple Alleles: 3 or more alleles for a trait in the population

Polygenetic Inheritance: when 2 or more genes affect 1 trait

Epistasis: When one gene can affect another.

Front 3

I can explain how a linkage map relates to cross-overs that take place during meiosis
