| 摘要: |
| 一个雄亲与数个雌亲相配所组成的家系是一个全同胞——半同胞混合的家系。雌亲内的后代是全同胞,雌亲间的后代是半同胞,这样一个家系内的亲缘相关随着配种的雌亲数和每个雌亲的后代数量的不同而变化。本文提出了计算这种混合家系亲缘相关的一个近似公式,并证明即使是对后代作随机抽样的情况下也是适用的。 |

| AN APPROXIMATE FORMULA FOR ESTIMATING GENETIC RELATIONSHIP IN A SIRE FAMILY |
|
|
|
| Abstract: |
| A Sire family is derived from a male mating with several females, So that the progeny within females are full-sibs and between females are half-sibs.The genetic relationship in such a mixed family varies with the number of females mated with the male and the number of progeny from each female.An approximate formula is given to estimate the average genetic relationship and this is available both to equal and unequal numbers of progeny per female.Also it has been proved that this formula can be used in the ca... |
