- In giraffes, long neck is dominant to short neck. Long neck is denoted by the dominant allele, N, while short neck is denoted by a recessive allele, n. Write the genotype and phenotype for the following organisms: homozygous dominant organism, homozygous recessive organism, and heterozygous organism.In humans, having facial dimples is dominant to not having facial dimples. Mary has dimples, yet only 3 of her 10 children have dimples. What must Mary's genotype be? homozygous dominant heterozygous homozygous recessive has dimples does not have dimplesWhat inheritance pattern results from alleles with incomplete dominance? There is a range of phenotypes such that the trait appears along a spectrum rather than "either or" There is a 3rd phenotype, often and intermediate value between the other 2 extremes The recessive phenotype is sex linked The recessive phenotype skips a generation
- Wavy hair is incomplete dominance of curly hair. If a wavy-haired woman has children with a straight-haired man, what are the possible genotypes and phenotypes? Be sure to use the correct shorthand that shows neither gene is recessive.What inheritance pattern results from alleles with incomplete dominance? The recessive phenotype skips a generation The recessive phenotype is sex linked There is a 3rd phenotype, often and intermediate value between the other 2 extremes There is a range of phenotypes such that the trait appears along a spectrum rather than "either or"in earlobes, attached (A) earlobe is dominant while free (f) earlobe is recessive. - free earlobes with heterozygous dominant for attached earlobes? (percent) - heterozygous for attached earlobes with heterozygous for attached earlobes. (percentage) - Homozygous dominant for attached earlobes with free earlobes. (Answer in percent)
- Wooly, curly hair is due to a rare dominant allele (H) and its recessive allele (h) produces straight hair. Another gene has 2 alleles: (B) dark hair is dominant over (b) blonde. A woman with wooly, blonde hair marries a man with straight, dark hair. Their daughter has straight, blonde hair. What phenotypes and in what proportions can they expect among future children?The hornless trait in cattle is dominant. The horned trait is recessive. A certain hornless bull is mated to three cows. Cow A, which is horned gives birth to a hornless calf. Cow B, also horned, produces a horned calf. Cow C, which is hornless, produces a horned calf. Name the genotypes of all parents and show the Punnett squares and possible genotypes of each offspring resulting from the cross.Color blindness is typically an inherited genetic condition in which individuals have a decreased ability to see color or differences in color. Color blindness only occurs in individuals who have two recessive alleles for the condition. Normal color vision is due to a dominant allele (C) Color blindness is due to the recessive allele (c) a) If Susan is homozygous for normal vision, and Matt is homozygous for color blindness, what is the likelihood (in percentage) that their son Alex will have color blindness? Perform a Punnett Square (either below or by hand on paper) to find the probability. Provide your answer in a full sentence. If you did the Punnett Square by hand, attach your photo to the next question.
