Title: Gene interaction, when recessive allele in homozygous state in one locus inhibits expression of domi Post by: Humbah on Mar 16, 2016 Hello!
Im wondering what you people would answer for this question and please explain why also! The question is attaced in document Best regards Title: Gene interaction, when recessive allele in homozygous state in one locus inhibits expression of domi Post by: bio_man on Mar 16, 2016 /me The question needs to be posted word for word
Title: Gene interaction, when recessive allele in homozygous state in one locus inhibits expression of domi Post by: Humbah on Mar 17, 2016 Gene interaction, when recessive allele in homozygous state in one locus inhibits expression of dominant allele in other locus is:
a) Genetic heterogenity b) Incomplete penetrance c) epistasis d) Locus heterogenity e) Polygenic inheritance trait f) C+E Title: Re: Gene interaction, when recessive allele in homozygous state in one locus inhibits expression of Post by: bio_man on Mar 17, 2016 I can't see any one them being an option. The only possibility I see is incomplete penetrance, which is when some individuals with a particular (dominant) mutation express a wild type phenotype.
Title: Re: Gene interaction, when recessive allele in homozygous state in one locus inhibits expression of Post by: Humbah on Mar 17, 2016 Well in my opinion epistasis is the correct one, but according to answer sheet the correct answer is polygenic inheritance trait!
It cant be incomplete penetrance because then no phenotype is really hidden its just a intermediate of the parental phenothypes! ;) Title: Re: Gene interaction, when recessive allele in homozygous state in one locus inhibits expression of Post by: bio_man on Mar 17, 2016 I can see how epistasis could fit as well; in fact, it fits a lot better than what I suggested. Still not sure how it can be polygenic inheritance though. Polygenic inheritance is when a single trait is controlled by 2 or more sets of alleles.
