More Crosses with Pea Plants: The Principle of Independent Assortment Determine the possible genotypes of the following parents by analyzing the phenotypes of their children. In this case, we will assume that brown eyes (B) is dominant to blue (b) and that right-handedness (R) is dominant to left-handedness (r). a. Parents: brown eyes, right-handed brown eyes, right-handed Offspring: 3/4 brown eyes, right-handed 1/4 blue eyes, right-handed b. Parents: brown eyes, right-handed blue eyes, right-handed Offspring: 6/16 blue eyes, right-handed 2/16 blue eyes, left-handed 6/16 brown eyes, right-handed 2/16 brown eyes, left-handed c. Parents: brown eyes, right-handed blue eyes, left-handed Offspring: 1/4 brown eyes, right-handed 1/4 brown eyes, left-handed 1/4 blue eyes, right-handed 1/4 blue eyes, left-handed
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?
Andalusian chickens may be either black, white, or gray. The gene for black is not dominant over the gene for white, nor is the gene for white dominant over the gene for black. When a black rooster is mated to a white hen, all gray chicks are produced. When gray chickens are mated, the chicks are black, gray, and white. Using a Punnett Square, demonstrate how feather color is inherited in Andalusian chickens. Is the inheritance of feather color in this problem an example of incomplete dominance? Why would it be impossible to establish a true breeding flock of gray Andalusian chickens? In guinea pigs, black coat color (B) is dominant to white (b), and a rough coat (R) is dominant to smooth (r). What are the expected genotypic and phenotypic results of the following crosses? BBRR x bbrr BBrr x bbRR Bbrr x bbRr BBRr x BbRr BbRr x BbRr A pure-breeding black, smooth guinea pig was mated to a pure-breeding white, rough female.They produced several litters,…
A cross between a black-furred male dog and a white-furred female dog could produce offspring with a black-and-white coat. This means that the color coat traits of the parents are codominant as both were expressed together. Show a cross between a Black-white furred dog and a homozygous white dog. Indicate the genotypes of both parents and the possible outcome in percentage.
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.
Working with the definitions of penetrance and expressivity, analyze the following pedigree and assume that the father of the proband is homozygous for a rare trait. (Consider a rare trait here to be less than 1 in 30,000.) What pattern of inheritance other than autosomal recessive could explain this pedigree? In particular, explain the genotype and phenotype of the proband (arrow).
predict the possiblity of an offspring with a widows peak, a dominant inherited trait affecting the hairline, when both parents are heterozygous for the trait. Would this be 25%, 75%, 100% or 0% the offspring will have a widows peak?
In humans, widow's peak (H) is dominant over a continuous hairline (h), and short fingers (F) are dominant over long fingers (f). Two heterozygous individuals with widow's peak and short fingers want to have a child with continuous hairline and long fingers. Is this possible?
In the inheritance of sex-linked eye colour in Drosophila melanogaster (fruit fly), what are the likely results (F1 generation) of a cross between a red-eyed male fly and a white-eyed female fly? Note: white-eyed is a recessive trait. Select one: All red-eyed male, all white-eyed female. All red-eyed male and female. All white-eyed male, all red-eyed female. All white-eyed male and female.
Shown in the pictures below are the degrees of dominance in the inheritance of flower color in some plants. *Based on the phenotypes (or maybe genotype), differentiate between complete dominance, incomplete dominance, and codominance. Be able to discuss the difference briefly but concisely. You may also refer to the definition.
The ability to detect the bitter taste of Phenylthiocarbamide (PTC) is inherited. “Tasting” is controlled by a dominant allele, while “non-tasting” is recessive PTC paper placed in your mouth can determine if you are a “taster” or a “non-taster”? Let's assume that you are a "taster". What possible genotypes could produce your phenotype? If you produced children with a "non-taster", what genotypic and phenotypic ratios would be expected in your offspring?
Red green colorblind as is a sex linked trait if a carrier female has children with a normal Male what are the chances of their offspring will be colorblind?
