The Rainbow Connection

The genetic variability or the Giddings children started out as mutations that occurred thousands of years ago. Take hair color: Our distant ancestors probably all had dark hair, its color controlled by multiple genes located on several different chromosomes. The alleles that produced Tess's blond hair originated as mutations in genes that control the amount and type of hair pigment. Tess probably inherited only “pale hair” alleles of all of these genes, so for any given hair color gene, she has the same pale hair allele on both homologous chromosomes. Chris, on the other hand, inherited both dark and pale hair alleles for at least some of the genes, so his homologues have different alleles. As we will see in Chapter 11, in many cases one allele (in this case, the dark hair allele) overrides the effects of the other allele (the pale hair allele), so Chris has black hair. What combinations of alleles might have been packaged in Tess's eggs and Chris's sperm, which would combine to produce their diverse children?

The zebra fish is a very popular aquarium pet fish that is known to be hardy, attractive, and able to survive well in groups. Wild type zebra fish have blue–purple horizontal stripes that run from gill to tail, with a silver–gold body. An alternative form of the zebra fish results from a mutation that causes a homozygous recessive red-colour fish.  Could you kindly answer all of the questions? It's multiple choice so minimal explanation is needed and i do not have a lot of questions left. Thank you. a) If 32 of 84 zebra fish have the recessive phenotype of red colour, what is the frequency of the recessive allele in this population of fish? a. 0.62 b. 0.38 c. 0.14 d. 0.79   b) What percentage of the population of zebra fish are heterozygous?   a. 47% b. 38% c. 62% d. 53%   c)How many zebra fish are purebreeding for the blue–purple horizontal stripes?   a. 72 b. 12 c. 52 d. 5   d) If 15 years ago, 34 of 88 zebra fish had the red colour, has microevolution occurred? Why or why not?…
Interested in exploring the genetic pathways that lead to neurological issues, you want to see if recessive mutations which generate too many neurons (tm) in flies - which many causes autistic like symptoms are in the same gene as mutations that generate too few neurons (tf) - intellectual diabilities. You cross a true-breeding homozygous tm/tm fly to a homozygous too few neuron fly tf/tf. What phenotype in the progeny would tell these mutations are in different genes?
Certainly, not all Muppets look like the one shown in the picture below, nor do they all look the same. In fact, there’s a great deal of phenotypic variation in Muppets. Two traits that have been particularly well-studied are curly hair presences  and skin color.     One individual is a male, and he possesses a green skin and no hair, whereas the female individual possess a curly hair and pink skin. Let’s call the gene controlling skin coloration S and that controlling hair H. In this species, both hair and green skin are recessive traits. Both of the individuals shown are homozygous.   1. What is the genotypes of  Miss Piggy:   2. Kermit's Genotype:   3. If these two lovebirds (er, love-muppets?) mated, what would their offspring look like? Describe all phenotype combinations possible and the ratios in which they would occur?
