Please help me answer numbers 1-4. Please please. Thank you! OTHER NON MENDELIAN INHERITANCE1. In rabbits, coat color is affected by a series of alleles with a hierarchy ofdominance such that C+> C ch >Ch > c. Each allele is dominant over all the alleleslisted to its right. C+ codes for full color. Cch codes for chinchilia, Ch codes forhimalayan (white with black extremities) and small c codes for albino. A chinchillarabbit is mated to a himalayan rabbit. Each of these rabbits has one albino parent.What are the phenotypes of the offspring and the probability that each wili beproduced?Answer2. The autosomal dominant allele ML specifies a tailless phenotype in cats. Thisallele is lethal in the homozygous state. A tailless female cat is mated to a taillessmale cat. What are the phenotypes of the offspring and the probability that eachwill be produced?Answer3. Agouti (A) is wild type and produces alternating bands of pigment on each hair.Black (a) is recessive to agouti. A mutation on gene B (recessive b) can eliminateall color. In a cross between agouti (AABB) and albino (aabb) mice, whatgenotypes, phenotypes, and proportions are expected in the offspring in F1 andF2 generations?Answer4. What unusual phenomenon is at work in each of the following disorders?a. Mara develops dark patches on her face. Her family physician suspects thatshe may have alkaptonuria. However, a dermatologist discovers that the womanhas been using a facial cream containing hydroquinone, which causes skinpatches in dark-skinned people?Answer

More Crosses with Pea Plants: The Principle of Independent Assortment Consider the following cross in pea plants, in which smooth pea shape is dominant to wrinkled, and yellow pea color is dominant to green. A plant with smooth yellow peas is crossed to a plant with wrinkled green peas. The offspring produced peas that were all smooth and yellow. What are the genotypes of the parents? What are the genotypes of the offspring?
Crossing Pea Plants: Mendels Study of Single Traits If you are informed that tune deafness is a heritable trait, and that a tune deaf couple is expecting a child, can you conclude that the child will be tune deaf?
Crossing Pea Plants: Mendels Study of Single Traits Sickle cell anemia (SCA) is a human genetic disorder caused by a recessive allele. A couple plan to marry and want to know the probability that they will have an affected child. With your knowledge of Mendelian inheritance, what can you tell them if (1) each has one affected parent and a parent with no family history of SCA or (2) the man is affected by the disorder but the woman has no family history of SCA?

True or false? Codominance and complete dominance establish the same pattern of inheritance.
Co- Dominance1) In cattle, the alleles for red coat (R) and white coat (W) behave as the co-dominants. Both red and white hairs are produced in the heterozygote producing a coat pattern that is called "roan." a) Give the phenotypic and genotypic ratios to be expected among the offspring from a cross of two roan animals. b) What are the expected genotypic and phenotypic ratios from a cross of a roan animal and a white one?
Mendel's concept of dominance states that in a genotype where two different alleles of a locus are present, only the trait encoded by the dominant allele is observed. Give a molecular explanation for dominance, i.e. explain intracellular molecular events that can result in what we observe as dominance on a phenotypic level. Use the gene that encodes seed shape in peas as an example, where roun(R) is dominant over wrinkled(r), to explain how RR and Rr plants can have the same phenotype.
Incomplete Dominance: 1) On the planet Iota Geminorum IV there exists a small hairy animal known as a tribble. It comes in three colors blue, red, and purple. This trait is controlled by a single locus with incompletre dominance. A homozygous CBCB is blue, a homozygous CRCR is red, and a heterozygous CBCR is purple. a. What would be the genotypes and phenotypes of the offspring if a blue tribble were crossed with a red one? b. If the offspring in #1 were crossed what would the genotypic and phenotypic ratios be of this generation?
Fur color is codominant in cows. A roan cow has a fur color of orange and white. What are the phenotype and genotypic ratios expected if a roan male and a roan female breed together?
