What is an example of recessive bs dominant epistasis? Please explain as simplistic
In genetics, epistasis is a phenomena in which the effect of a gene mutation is conditional on the presence or absence of mutations in one or more additional genes, referred to as modifier genes. In other words, the effect of the mutation is context-dependent.

- Consider a Droscophilia fly with a genotype of Nn XqYY. The dominant allele of the sex-linked gene specifies a black body and the recessive a white body. The recessive autosomal allele specifies hairy bristles while the dominant allele specifies smooth bristles. i)What is the ploidy of this fly? ii) What would the sex of this fly be? iii)What would the phenotype of this fly be with respect to these two loci?Which of the 6 modes is this pedigree and why? 1) Autosomal Dominant 2) Autosomal Recessive 3) X-linked Recessive 4) X - linked Dominant 5) Y-Linked 6) mt-Linkedy 301 Amelogenesis imperfecta is X-linked dominant. Affected XY individuals have extremely thin enamel on the teeth while XX carriers have grooved teeth from uneven deposition of enamel. If an unaffected XY individual were to produce children with a XX carrier partner, a. what would be the expected chance of a XY child being affected with the disease? b. what would be the expected chance of a XY child being affected with the disease?
- There are six types of agglutinogen named C,D, E and c,d,e.the first three are dominant and last three are recessive.discusssymptoms of fragile X syndrome are more severe in progeny generation than in the parental generation. Is an example of 1) variable expressive 2) epistasis 3) pleiotropy 4) reduced penetrance 5) anticipationIn a multigenerational study of a family, 8% of the males and 8% of the females have red hair. What may be the cause of this? A)Autosomal inheritance B)Environmental influence C)Sex-linked inheritance D)Non-somatic inheritance
- What some ways that incomplete penetrance can occur? Give at least two possible ways on why it occurs.Consider the following pedigree. 하 3 10 (5 3 2 (a) What pattern of transmission is most consistent with this pedigree? (1) autosomal recessive, (2) autosomal dominant, (3) X-linked recessive, (4) X-linked dominant. (b) If individual V-2 marries a normal individual, and if the condition has a pene-trance of 85 percent, what is the probability that their second child will express the trait? (c) On the third line, what does the diamond with a 10 in the middle mean?Some conditions like progeria do not run in families despite being autosomal dominant. How is this possible?
