Pick one trait, when you inherited from your parents, Once you have done that, write out the possible geno types & Pheno types of that trat fromeach of ycour parents, Do all possible crossings. Once you have done all the crossing, circle all the genotypes Hhat would haue allowed youta inher it Hhat tráits.

7) Three years later, one of Rocky's and Ruby's sons, who is heterozygous for his curly fur, meets another dog that is also heterozygous for her curly fur. Create a Punnett square to show the possibilities that would result if they had puppies. (4) a) Fill in the Punnett square, then list the possible genotypes and phenotypes for the puppies. b) What are the chances of a puppy with curly fur? out of c) What are the chances of a puppy with straight fur? out of BLOMU CAGA (C 3LS gousur co BeGAGE (p) BROM ncrinoh (e) etone 2po BLOM

In humans, albinism (lack of skin pigment) is an autosomal recessive trait. The first child of two normally pigmented parents is an albino. Which of the following is true about this family? SELECT ALL THAT ARE CORRECT. A) Their first child (described above) has a homozygous recessive genotype B) The next child born to this couple has a 25% chance of being albino. C) If the next child born to this couple is male, he has a greater chance of being albino. D) The parents are both heterozygous for albinism. E) The probability of their second child being albino is 0% F) If the second and third child born to this couple are albino, the fourth child has 100% chance of also being albino.

In human beings, the gene for red‑green colorblindness (r) is sex‑linked and recessive to its allele for normal vision (R), while the gene for freckles (F) is autosomal and dominant over its allele for nonfreckled (f).  A nonfreckled, normal‑visioned woman whose father was freckled and colorblind, marries a freckled, colorblind man whose mother was nonfreckled. What is the probability that the first child born to the couple will either be a freckled, colorblind boy or a non‑freckled, normal visioned girl or a non-freckled, normal visioned boy?   What is the probability that the first four children born to the couple will be freckled and normal visioned girls?

The three genes X, Y, and Z are linked on an autosomal chromosome in humans (X to Y is 15 cM, and Y to Z is 18 cM). If an individual that is heterozygous at all three loci (XYZ/xyz) has children with an individual that is homozygous recessive at all three loci (xyz/xyz), what is the probability that they will have a child that is phenotypically identical to either parent (X-Y-Z- or xxyyzz)? Assume there is no genetic interference to double crossover events at this site.

An unaffected woman for a human disorder marries and unaffected man and they have children. This results in 3 affected sons, and one unaffected daughter, which ends up having children later on with an unaffected man and has 2 affected sons. A) Draw a simple pedigree diagram for this family, including a legend. B) What is the likely mode of inheritance of this trait: Please explain C) Provide the genotypes of the original mother and the daughter. Use a capital letter for the dominant allele and lowercase letter for the recessive allele. D) If one of the affected sons from the original marriage marries a 2nd cousin that is a carrier of this trait and has children, what is the probability that they will have 3 affected sons?

The Pedigree shown is O O 마ㅇ ㅇㅇㅇ 이탕 - ㅁㅁㅇㅁ 5 A) Autosomal Dominant B) Sex linked recessive C) Autosomal Recessive D) Sex linked dominant

Frank and Susan both have freckles but they're firstborn son Lawrence does not demonstrate the characteristics. What are the most likely genotype of Frank Susan and Lawrence?

A male with autosomal dominant brown hair and a female with unknown hair color have 3 sons with recessive blonde hair. What is the male’s genotype?  What are the possible genotype(s) and phenotype(s) [hair color] of the female?
