rabbit genetics simulation

2005; Burke et al. Test your rabbit color genetics knowledge. 2009). GPC4 is of special interest because it is the second most variable locus in OCCFR but invariant in DOM. 2001; Stephens and Donnelly 2003).

These results of simulation indicate that the domestication of rabbits was accompanied by a fairly severe bottleneck of 1,200 individuals or less, which is much smaller than the effective populations size of wild rabbits in France (OCCFR, Ne = 538,239) or in Northern Spain (OCCIP, Ne = 1,043,467) inferred using a simple mutation-drift expectation (θ = 4Neμ, where θ is the average θw value for all autosomal loci, μ is the average mutation rate, and μ = 1.74 × 10-9 was obtained from the comparison between rabbits and Lepus). 1997; Whitman 2004). Moreover, rabbits have many hereditary diseases common to humans (e.g., aortic arteriosclerosis, cataracts, hypertension, hypertrophic cardiomyopathy, epilepsy, spina bifida, osteoporosis, and many more), making them a valuable model in both biomedical and fundamental research.

Remove the other offspring by pressing Clear Offspring Click on Breed repeatedly (about 40 times), then record the number of each colour of offspring number of black offspring: _____ number of white offspring: ____ [1] Analysis of Task 2 Explain your results, giving a full genetic diagram. The simulations were performed using the algorithm described by Hudson (1990) and implemented in the program ms (Hudson 2002). . Now lets place some possibilities into a Punnett square to see if we can successfully determine the genotype of the offsprings. Show rabbits are typically true dwarfs . We applied the algorithm independently for OCA, OCCIP, OCCFR, and DOM. If there was a higher contribution of females when domestication started, then we should expect a relatively higher amount of genetic diversity captured for the X chromosome when compared with the autosomes. The bottom panel shows LD considering all six breeds together.

In this version, no color modifiers or breeds of the different rabbits have been added, only a summary of the most usual color layers. Levels of nucleotide diversity (π) in DOM averaged 0.188% and 0.205% for autosomal and X-linked loci, respectively (table 1) but there was substantial heterogeneity among loci with π ranging from 0% to 0.760% (supplementary table 5, Supplementary Material online). What kind(s) of gametes (sperm) can he produce? and/or and/or and/or. Such a strategy has been applied with outstanding success in dogs (Karlsson et al. 2006, 2008). The department has three major research missions, which are (1) to develop and use genetic methods to investigate the causes and treatment of hereditary and acquired human illness, (2) to understand and explore the impact of genetics … First, we performed an HKA test (Hudson et al.

To use the SpeakUP app, students are required to enter a common room number or create a room and share the number of the room with the other student(s). In other words, the chart of colors is organized to progress logically from color to color and to show you the relationships between colors. and/or and/or and/or, If we arbitrarily let the buck be aabbcc, what kind(s) of gametes can he produce?

Minimum number of recombination events in the history of the sample (Hudson and Kaplan 1985). We detected a total of 267 SNPs and indel markers and 74.5% had a minor allelic frequency of 10% in at least one breed. 1, Supplementary Material online). Conversely, sequence diversity in domestic rabbits can be explained by a bottleneck of a shorter duration and lower numbers of individuals. Levels of diversity were not significantly different between autosomal and X-linked loci, providing no evidence for differential contributions of males and females to the domesticated gene pool. The number of segregating sites (S) and haplotypes (nhaps) produced nonflat unimodal likelihood distributions for most loci, whereas for π we obtained somewhat flat curves on larger values of kdom and kfr (supplementary figs.

Plots of LD decay within and among domestic breeds for seven genomic regions. Choose Your Breeds. 2005; Yamasaki et al. In both versions, there are rabbits with straight and floppy ears. These were chosen from a set of loci used in previous studies on wild rabbits from the Iberian Peninsula (Carneiro et al.

First, neutral mutation rates were determined for each locus from the relationship μ = D/2T, where D is the estimated Dxy for the Oryctolagus/Lepus comparison (values available in Carneiro et al.

LD was measured using the genotypic r2 (Weir et al. Although the effects of selection cannot be discarded (see below), it is unlikely that all these regions have been under selection during rabbit domestication. You should select appropriate symbols, and make clear in your answer, which is the dominant phenotype. As long as two users enter the same room number they will share the same simulation. What kind(s) of gametes can she produce? To double check, number of squares = 64,sum of genotypes = 64,and sum of phenotypes also = 64.

For both Punnett squares we will assume the doe has a genotype of aa. Size variation in domestic rabbits is greater than that in the entire Leporidae family. This method for identifying genomic regions under selection does not rely on equilibrium conditions and looks for outliers against a null model that specifically incorporates the two bottlenecks depicted in figure 2. Polymorphic single nucleotide polymorphisms (SNPs) or insertion and deletion (indel) markers having more than 10% of missing data and/or minor allelic frequencies within a breed lower than 10% were excluded from the analysis. The domestic rabbit is one of the most recently domesticated species (most likely within the last 1,500 years; see below) and is characterized by an exceptionally high phenotypic diversity with more than 200 breeds recognized worldwide (Whitman 2004). Investigations of effective population size variation through time using LD information in other domestic species, such as cattle and chickens, have also showed recent declines in effective sizes within breeds, suggesting this to be a common trend among domesticated animals (Gibbs et al. 2005; reviewed in Ferrand and Branco 2007). Some possible questions a teacher could ask are: 1) Is it possible in this simulation for two black rabbits to produce a white offspring? Coalescent simulations suggest that domestication began with a small founding population of less than 1,200 individuals. Removing GPC4 and LUM, which deviate significantly from expected values given the magnitude of the domestication bottleneck (see below), domestic rabbits have lost 37.1% of genetic diversity based on π and 43.8% based on θw, on average. Club, Michigan State 5) and, as previously shown (Eyre-Walker et al.
