After cell division was complete the daughter cells were nactivation Recombination m) n) The dominant disease allele causes severe disease in someTemperature-sensitive allele o) Sex determination individuals and only mild disease in others Variable expressivity Multifactorial inheritance means that most individuals do not have very acute or very poor eyesight. . X-linked inheritance

Explanation / Answer

a) She was surprised to hear that her mother and father had two great grandparents in common - consanguineous mating

b) He had a normal hearing even though a recessive allele caused deafness in his father - heterozygous

c) Heterozygosity for the mutant allele caused patches of skin on her body to be unable to sweat - incomplete dominance

d) A mutation causes intellectual disability in all boys who inherit it but leaves their sisters largely unaffected - X linked inheritance
