AP PSYCHOLOGY

Detailed explanation-1: -To have an autosomal recessive disorder, you inherit two changed genes, sometimes called mutations. You get one from each parent. Their health is rarely affected because they have only one changed gene. Two carriers have a 25% chance of having an unaffected child with two unaffected genes (left).

Detailed explanation-2: -Genetic Disorders. These are carried by recessive genes. Diseases carried by recessive genes genes are inherited when a child inherits two recessive genes, one from each parent. Genetic Disorders inherited from two recessive genes.

Detailed explanation-3: -Recessive alleles only show the traits if the person has 2 copies of the same alleles. This is considered being homozygous, having the same 2 copies of alleles. If a person has 2 copies of the blue eye allele (both recessive) then the person would have blue eyes.

Detailed explanation-4: -Autosomal dominant traits pass from one parent onto their child. Autosomal recessive traits pass from both parents onto their child. Autosomal refers to the 22 numbered chromosomes as opposed to the sex chromosomes (X and Y).
