A type of mouse may have round ears or pointed ears. A female mouse homozygous for pointed ears is crossed with a male mouse homozygous for round ears. All the male offspring have pointed ears and all the female offspring have round ears. When the F1 offspring are crossed with each other, the resulting F2 are produced in the following ratios: Males: 3 pointed : 1 rounded Females: 3 rounded : 1 pointed Explain the inheritance mechanism that produces these results and indicate the dominance relationship.

Consider a situation where you have a parental cross with the mother and father phenotypes listed below The counts of the F1 offspring are listed in Table 1. Two randomly selected individuals are selected and mated to produce a set of F2 individuals. If you test the F2 counts to determine whether they are consistent with an autosomal dominant mode of inheritance, what is your decision? Use a 0.05 significance level. PARENTAL CROSS Parental cross: Mother with disease phenotype, Father with wild-type phenotype. Table 1. F1 DATA Gender Phenotype Disease Wild-Type Male 0 23 Female 0 34 Table 2. F2 DATA Gender Phenotype Disease Wild-Type Male 7 25 Female 0 25 a) Do not reject the null hypothesis that the F2 data are consistent with an autosomal dominant mode of inheritance; chi-square goodness of fit test p-value is greater than 0.05. b) Do not reject the null hypothesis that the F2 data are consistent with an autosomal dominant mode of…
In horses, coat color comes in many varieties. If a brown horse is crossed with a white horse, the offspring are palominos (brown and white manes and tails). Name the type of inheritance. If a palomino horse is crossed with a white horse, what will the phenotype ratio of the F1 be?
the lubber grasshopper is a very large grasshopper,and is black and red and yellow stripes.Assume that red strpes are expressed from Gr alleles,yellow stripes from the Gy allele,and no stripes from the g allele.What will be the phenotype ratio resulting from a cross of two grasshoppers,both with red and yellow stripes? what type of inheritance is occurring in this situation ?
In chickens, the Leghorn variety has white feathers due to an autosomal dominant allele. Silkies have white feathers due to a recessive allele in a second (different) gene. If a true-breeding whiteLeghorn is crossed to a true-breeding white Silkie, what is theexpected phenotype of the F1 generation? If members of the F1generation are mated to each other, what is the expected phenotypic ratio of the F2 generation? Assume the chickens in the parental generation are homozygous for the white allele at one gene andhomozygous for the brown allele at the other gene. In subsequentgenerations, nonwhite birds will be brown.
