SEX LINKED INHERITANCE by Mind Map: SEX LINKED INHERITANCE

1. Reproduction

1.1. Sexual

1.1.1. Animals

1.1.2. Fertilization

1.1.2.1. Combination of Haploid gemets

1.1.2.2. 24-30 hours

1.1.2.3. the female receives proteins through the seminal fluid of the male

1.1.2.3.1. increase their activity,

1.1.2.3.2. reduce their sexual receptivity

1.1.2.3.3. stimulate their immune system

1.1.3. A lot of babys

2. Genetics

2.1. Purpose

2.1.1. Biological inheritance

2.1.1.1. Analyze, undertand and explain it

2.2. Nucleus

2.2.1. Contain

2.2.2. 46 chromosomes (from mother and father)

2.2.3. Chromosomes

2.2.3.1. Diploid

2.2.3.2. Haploid

2.2.3.2.1. 23 chromosomes (or the mother or the father)

2.2.3.3. DNA

2.2.3.3.1. Nucleic acid

2.2.3.3.2. Genotypes

2.2.3.3.3. Gene

2.2.3.3.4. Allele

2.2.4. Traits and physical characteristics

3. Mendel inheritance laws

3.1. Law of Segregation

3.1.1. Two genes of a gene pair segregate from each other into the gametes, so half the gametes carry one member of the other pair, and the other the other half.

3.2. Law of Independent Assortment

3.2.1. Different genes pairs assort randomly during the gamete formation.

3.3. Law of Dominance

3.3.1. In a cross of parents that are pure for contrasting traits, only one form of the trait will appear in the next generation.

4. Sex linked inheritance

4.1. Y chromosome

4.1.1. Fewer genes

4.1.2. Shorter than the Y chromosome

4.2. X-linked disorders

4.2.1. Less common in females

4.2.1.1. More common in males

4.2.1.1.1. They have just one X chromosome

5. Drosophila Melanogaster
