Purple fur (P) is DOMINANT in monsters. Yellow fur (p) is RECESSIVE. What is the genotype of a PURE PURPLE monster? = What is the GENOTYPE of a HETEROZYGOUS purple monster? What is the GENOTYPE of a YELLOW monster? = Using the punnet square above, make a cross between TWO HETEROZYGOUS PURPLE MONSTERS. POSSIBLE OFF SPRING GENOTYPES PHENOTYPES

In griffins, coat colour is determined by a single gene with a completely dominant black (B) allele and a recessive white allele (b). Beak shape is determined by a single gene with a completely dominant sharp beak allele (R) and a recessive round beak allele (r). The colour and beak genes are linked by 25 cM(= centimorgans = map units). If a female heterozygous at both loci has the dominant alleles linked in cis, she will produce gametes that have what genotypes in what ratios? Explain your answer.

Suppose a geneticist is using a three-point test cross to map three linked rabbit morphology and behavioral mutations called si, sf, and H. The gene si is associated with the silky fur phenotype, and sf is associated with the short-footed phenotype. Both si and sf are recessive mutations with respect to wild type. H is a dominant mutation that confers the hyper phenotype. The geneticist first crosses true-breeding hyper rabbits to true-breeding silky fur, short-footed rabbits. Next, the geneticist backcrosses the F₁ progeny to the silky fur, short-footed parents, and obtains the results reported in the table. Phenotype hyper silky fur, short-footed short-footed silky fur, hyper silky fur short-footed, hyper silky fur, short-footed, hyper wild type Place the genes in the correct order in the chromosome.

You are a zoologist working with Giraffes. Their main traits are: Grey tongues (G+), Rudimentary Horns (R+), Long necks (L+) . You perform the following testcross with an individual with recessive versions of all 3 of the traits. P: G+ R+ L+/G+ R+ L+   x G R L /G R L F1(all identical): G+ R+ L+/G R L What this the distance between G and R? What is the distance between G and L? What is the distance between R and L? What is the correct order of the genes on the chromosome? (5 points) (Hints: You should draw it first. The overall order will not change whether reading from the left or the right side of the chromosome).  a. G--R--L b. L--G--R c. G--L--R

In guinea pigs, the allele for short hair (S) is dominant. Show the cross for a homozygous short haired guinea pig and a long haired guinea pig. Show all five steps to solving the problem.

Tri-hybrid: Zombie “speed” is a trait determined by the alleles F and f at the speed gene, where fast is dominant to slow.  Zombie “brain eating” is a trait determined by the alleles B and b at the brain-eating gene, with eating brains recessive to not eating brains. Zombie drooling is a trait determined by the alleles D and d at the drooling gene where not drooling is recessive to drooling. Cross: A female Zombie that is ffbbDd has offspring with a male Zombie that is FFBbdd. What percentage of the offspring will be fast?  What percentage of the offspring will be brain eaters?  I'm having trouble with how these is set up as a punnent, and then calculating probability.

ABO blood group is co-dominant for AB and O is recessive. Rh (+/-) factor is completely dominant. A man with O/positive blood and a woman with A/negative blood have six children. All of their children have A + blood type. What can you conclude about the parents’ genotypes? Group of answer choices Both mother and father are likely homozygous  at both loci Mother was homozygous at the ABO locus but heterozygous at the Rh factor locus Father was homozygous at the ABO locus but heterozygous at the Rh factor locus Mother was heterozygous at both loci

The remaining questions go together. You are given a pea that produces round, yellow seeds (both dominant traits), but its genotype is unknown. You conduct a testcross to determine the genotype at both loci, and find that the offspring have the following ratios of phenotypes: 4 round, yellow, 4 round, green, 4 wrinkled, yellow, 4 wrinkled, green What is the genotype of the individual of known genotype in the testcross? rryy O RRYY O RrYy rrYy R_Y_ Rryy
