Genetics Quiz

  1. On your pedigree a chocolate bunny was bred to a lilac bunny the offspring of which was a blue. Is this Possible?
    True/False.
  2. I bred a black to a REW and got a pair of lilac torts....is this the most recessive genes that you could possibly get?
    True/False
  3. Breeding a seal to a himi is a good breeding combination.
    True/False.
  4. You will always know the genetic code of the rabbit by what he looks like.
    True/False.
  5. I bred a chocolate otter buck (from black otter X opal breeding) to a blue doe (from a tort X REW) and got a blue, a lilac otter, and a black otter. I bred the chocolate otter to a REW and got a poorly marked black himalayan. Give me as much of the genetic codes of the chocolate otter and the blue doe as you can.
  6. A black bred to a black can give you a litter of black, blue, chocolates and lilacs in the same litter.
    True/False.
  7. A REW out of a sia sable is the same genetically as a REW out of a self black?
    True/False.
  8. You can tell if a black rabbit carries the chocolate gene by his appearance.
    True/False.
  9. It is possible to get a REW out of opal X chestnut?
    True/False.
  10. A rabbit that looks like a poor colored black is easy to determine what he is genetically.
Answers:
  1. False. A chocolate rabbit is [a][a]-[b][b]-[C][?]-[D][?]-[E][?]
    A lilac rabbit is [a][a]-[b][b]-[C][?]-[d][d]-[E][?]
    A blue rabbit needs the Black gene [B], neither the chocolate or the lilac has this gene to give to this blue bunny. However, in the real world a lilac can look like a blue, a blue can be so light as to look like a lilac..therefore, one of these rabbits in genetically NOT what he appears!
  2. False. A lilac tort has the full color gene [C] in the c position, a more recessive colored rabbit would be a REW out of a pair of lilac torts.
  3. True. That should give you 100% showable shaded rabbits.
  4. False. A black looks alot like a seal, a self chin also looks alot like a self black. A seal marten can pass very easily as a black silver marten. Although the seals or self chins, might look more like poor blacks. Only through test breeding can you be 100% sure, unless you have access to a DNA lab and lots of money to burn.
  5. The chocolate otter would be [a(t)][a] he produced several "self" rabbits, he had to pass on an [a] gene and since he himself is a tan, you know that he has to carry that [a] gene in order to pass it on. [a(t)][a]-[b][b] since he is a chocolate, he has no other possibilities for this spot. [a(t)][a]-[b][b]-[C][c(h)] since he is an otter, he is a full colored rabbit and since he produced a himalayan when bred to a REW you know that SOMEONE had to donate that himi gene and it ain't the REW! [a(t)][a]-[b][b]-[C][c(h)]-[D][d] since he helped produce "dilutes" or blues, but he himself is not a dilute...you know that he has to carry this gene. [a(t)][a]-[b][b]-[C][c(h)]-[D][d]-[E][?] Can't fill this one in FOR SURE, but breedings didn't not produce anything with the non-extension gene [e][e], but none of the does themselves could be considered good test breeders for this gene either. He could carry the [e] gene, the blue doe carries the non-extension gene, but 3 bunnies is not enough, you should get at least 8 bunnies from a breeding before you assume whether the animal is an [E] or an [e]. There was no non-extended rabbits on the chocolate otters pedigree, he himself is not a non-extended rabbit and never produced any non-extended offspring. It's almost...but not quite...safe to assume that this rabbit would be [E][E]. Breeding him to the blue doe a couple of more times would be able to prove one way or another. The blue doe---The blue doe is a self rabbit [a][a], she also is a "black" rabbit, but since she produced a lilac otter when bred to a chocolate otter, you know that this blue doe carries the chocolate gene. [a][a]-[B][b] she is a "full colored" rabbit and since one of her parents is a REW you know that she has to have received a REW [c] gene from that parent. [a][a]-[B][b]-[C][c] and since blues are "dilutes" you know what goes in the "D" series. [a][a]-[B][b]-[C][c]-[d][d] the blue doe has a tort parent...the tort parent only has the [e] gene to pass on and since she herself is not a non-extended animal [e][e] you know that she at least has to carry it. [a][a]-[B][b]-[C][c]-[d][d]-[E][e] would be this does full genetic code...map out the codes for all the bunnies if you want...Email me your answers if you want me to check them for you!
  6. True. By getting all 4 colors in the same litter you know that both of the parents must carry both the chocolate and the dilute genes.
  7. True. A REW out of any self rabbit is the same genetically as any other REW out of a self rabbit...when a rabbit becomes a REW it loses it's ability to carry on any other genes in the "C" series except the REW gene.
  8. False. It's impossible to know what a rabbit carries just by looking at it, the only exception would be with the few genes that are incompletely dominant. A rabbit that is known as a chestnut could be carrying a lilac tort inside. each rabbit is carrying around 2 completely different sets of color genes, one that you can see (phenotype) and one that you can't see.
  9. True. By getting a REW out of ANY breeding, you know that each parent must carry the REW gene regardless of the color that it appears to be.
  10. False. A rabbit that looks like a 'poor black' may be just that a 'poor black' on the other hand, he might be a self chin or a seal. You just can't tell by looking at him.
