Bisexual branching processes in a genetic context: the extinction problem for Y-linked genes.
In this paper the inheritance of a Y-linked gene with alleles R and r in a population with both females and males is modelled using a two-type bisexual branching process. It is assumed that the reproductive distribution associated with the R allele can differ from the associated with the r allele and that females prefer to mate with a male having the R allele rather than with a male with the r ...
متن کاملInternational Biometric Society Rates of growth for Y-linked genes through bisexual branching processes
The XX/XY sex-determination system is one of the most familiar sex-determination systems and is found in human beings and most other mammals. In this sex-determination system, females have two sex chromosomes of the same kind, while males have two distinct sex chromosomes. Hence, if certain characteristics are due to genes linked to the Y chromosome, then they are only associated to the males. ...
متن کاملBisexual branching processes in a genetic context: rates of growth for Y-linked genes.
A multitype bisexual branching process is considered to model the behaviour of a Y-linked gene with two genotypes in a two-sex population. It is assumed perfect fidelity mating with preference of females for the males carrying certain allele of the gene. Under these assumptions, we study the rate of growth of each genotype on the event of non-extinction. The rate of growth of a genotype may dep...
متن کاملNon-Parametric Bayesian Inference for Y-linked Bisexual Branching Processes through MCMC Methods
It is well-known that in some animal populations the sex of the individuals is determined by a pair of chromosomes X and Y. A female has XX chromosomes, while a male has XY chromosomes. Certain characteristics are due to genes carried on the X chromosome (X-linked). Others due to genes carried on the Y chromosome (Y-linked) and still others to genes carried on both chromosome (XY-linked). Takin...
متن کاملOn the Extinction Probability for Bisexual Branching Processes in Varying Environments
In this paper, the bisexual branching process in varying environments introduced in [9] is considered and some sufficient conditions for the existence of positive probability of non-extinction are established.
