3. The gene that controls coat colour in rabbits has four alleles: agouti (C), chinchilla (cck), Himalayan (ch), and albino (c). The order of dominance among these alleles is C> cch > ch > c. A) heterozygous Himalayan rabbit is crossed with a chinchilla rabbit that had an albino father. a) What are the genotypes of the two rabbits? a Punnett square determine the phenotypic ratio of the rabbits’ offspring.

4) In frost moths, two alleles of one gene determine the character difference of spotted versus striped wings and two alleles of a separate, independent gene determine the character difference of orange wing background versus white wing background. The results for four matings of moth phenotypes are shown in the image attached. a) Assign the letter “s” to the wing pattern gene and letter “w” to the background color gene. Write in the capital letter for the dominant phenotype and the lower case letter for the recessive phenotype. Also, write whether each allele is dominant (D) or recessive (R). Wing pattern gene: Spotted  - letter assignment:____ - dominant or recessive:____ Striped - letter assignment:____ - dominant or recessive:____ Background color gene: orange: - letter assignment:____ - dominant or recessive:____ white: - letter assignment:____ - dominant or recessive:_____   b) Based on the four matings in Question 4: What are the genotypes of each parent in each cross? If more…

In humans, the recessive allele that causes a form of red-green colour blindness (c) is found on the X chromosome. a.) Determine the genotypes and phenotypes of the F1 generation from a colour-blind father and a mother who is homozygous for normal colour vision. b.) Determine the genotypes and phenotypes of the F1 generation from a father who has normal colour vision and a mother who is heterozygous for colour vision. c.) Draw a Punnett square to determine the genotypes of parents that could produce a daughter who is colour-blind

2) A man with a recessive sex linked allele for colour blindness marries a woman who has normal vision but is a carrier of the recessive allele. What proportion of the offspring would be expected to ...... a) be male b) have normal vision c) be colour blind

3. An inversion heterozygote has the following inverted chromosome: Centromere )))))))))))) A B JI HGF ED CKLM Inverted region What would be the products if a crossover occurred between the genes F and E on the inverted chromosome and the normal chromosome?

1. The figure below shows a pedigree examining the presence of a genetic disorder across multiple generations of a family. Based off this figure, answer the following questions prompted: || IV 3 9 10 5 2 C 6 11 T 7 12 8 15 13 16 14 17 d) What is the genotype for individual #4 in this family pedigree? ||| c) Why are no family members identified as a carrier of this genetic disorder? Figure Key a) Using the figure key provided, identify which members of this family are affected by this genetic disorder in each generation. (Be sure to include sex and generation number for each individual identified). b) Is this an autosomal recessive, autosomal dominant, or sex-linked genetic disorder? Explain. Unaffected Female Unaffected Male Affected Female ||| Affected Male Female Carrier Male Carrier

all of the offspring of a cross between a black eyed mendelien and an orange-eyed mendelien have black eyes. This means that the allele for black eyes is ___ the allele for orange eyes. A)Codominant toB)more aggressive thanC)recessive toD)dominant toE)better than

2). In rabbits, coat colour patterns are determined by 3 alleles at one locus. Agouti is dominant over Himalayan and both are dominant over albino. Give all the possible genotypes of a) agouti rabbits b) himalyan rabbits c) albino rabbits

1) Two parents are known to be right-handed (R), which is a dominant trait to left-handed. What are the genotypes of the parents if their son is left-handed? (choose) a. RR x rr b, RR x rr c, rr x rr d, rr x Rr   2) If two heterozygous traits are crossed, what will the result of the F1 offspring be? (choose) a, 1 TT: 2Tt: 1tt b, 1 TT: 2tt c, 1 TT: 1Tt: 1tt   3) An individual with the genotype AA is crossed with an individual with the genotype Aa, producing 120 offspring. The number of offspring with genotype AA will be close to. (choose) a, 90 b, 120 c, 30 d, 60
