Cards (12)
- Sex-influenced Traits are autosomal traits influenced by sex, with males showing traits with one recessive allele and females needing two recessive alleles to show the same trait
- Sex Linkage - an association between genes in sex chromosomes where characteristics appear more frequently in one sex than the other
- x linked Traits Examples
- hypertrichosis of the ears
- webbed toes
- porcupine
- y linked Traits Examples
- color blindness
- muscular dystrophy
- hemophilia
- congenital deafness
- spinal ataxia
- ocular albinism
- brown teeth
- congenital cataract
- retinitis pigmentosa
- diabetes insipidus
- Sex-Linked-Traits are characteristics influenced by genes on the sex chromosomes, with humans often referring to traits influenced by genes on the X chromosome
- Sex-limited Traits are determined by genes located on autosomes and express only in one sex, responsible considerably for sexual dimorphism
- Recombination - a process where pieces of DNA are broken and recombined to produce new combinations of alleles
- sex linked Traits refer to characteristics influenced by genes on the X chromosome, with females having two X chromosomes and males having one X and one Y
