In a sub species of Sunfish dorsal spines are controlled by number of dominant alleles in two contributing pair of allelels (A and B). A fish with four spines in the dorsal fin is AABB while a fish with all recessive alleles would have the genotype aabb. What would be the offspring of a fish who had a heterozygous genotype with another fish that had one dominant A allele and all the other alleles were recessive? What is % chance of having a 0 spined dorsal fish in the f1 generation? What is % chance of having offspring with 4 spines in their dorsal fin?
A male child with type O blood has parents with type A blood and type B blood. Explain how this could happen if his parents have different phenotypes than him. Show at least one punnet square showing the evidence of how this could work.
In a type of cattle white hair color is dominant so is brown color. When you get the heterozygous condition both hairs are present. What would be the genotypic and phenotypic ratios produced in the f1 generation if both bull and cow of p generation are heterozygous?
A type of flower has the genotype Rr and produces a pink flower, rr genotype produces a white flower, and RR produces a red flower. What would be the f1 generation phenotypes if you crossed pink flower with a white flower? What is the the resulting genotypic ratio?
In a type of insect antenna color is on the X chromosome. Brown antenna are dominant to tan antenna. What would be the % of male offspring with tan antenna if the mother had a tan antenna and the father had brown antenna?
In a species of humming birds the beak can be red or yellow and be 5mm or 8mm in length. A male who is heterozygous for beak length and color and his phenotype is 5mm yellow beak and is crossed with a female that is homozygous recessive for both traits. What % of the offspring will have their mothers phenotype? What % will have their fathers phenotype?
In a species of bat brown wings are dominant to black wings. What would the offspring be if you crossed two heterozygous bats? What % of the offspring will have the same genotype as the parents?
You will need add your own unique genetic problem to each blog I post in the comments section of the blog for a grade. Below are some basic guidelines:
Each genetics problem must be solvable and be free from major errors.
Do not plagiarize the genetic problems which you list here for a grade and others to solve.
Make sure to have your initials at the start of each genetic problem you create.
If you have any question you can post them as comments to this blog and then I will try to get back to you as soon as possible.
