1. Sex Chromosome Evolution in a Hermaphrodite : Genetic and phenotypic relationships between sex roles
Sammanfattning : Sex chromosome evolution in a hermaphrodite ancestor starts with the establishment of a sex-determining region (SDR). Over time, sex-specific genes, and/or sexually antagonistic alleles will become linked to the SDR. LÄS MER
2. Reproduction in the Hermaphrodite Aeolidiella glauca - A Tale of Two Sexes
Sammanfattning : This thesis focuses on reproduction in a simultaneous hermaphrodite with internal fertilization; the nudibranch Aeolidiella glauca. Unlike most other nudibranchs, where copulation is the rule, A. glauca was found to transfer sperm via external spermatophores that were attached to the partner's back. LÄS MER
3. Clonal structure and reproductive biology in the gynodioecious herb Glechoma hederacea L. Lamiaceae
Sammanfattning : Clonal structure and reproductive biology in the gynodioecious herb Glechoma hederacea L. Lamiaceae The frequencies of females, hermaphrodites and partially male-sterile (PMS) genets of Glechoma hederacea were estimated in natural populations in S Sweden. The frequency of females and PMS genets in natural populations varied from 0 to 100%. LÄS MER
4. Mating system evolution and self-incompatibility in the wild plant species Brassica cretica
Sammanfattning : Compared to animals like ourselves, plants have a very flexible sexual life. Most plants are, for example, hermaphrodites with the potential capacity for reproduction by self-fertilization (or selfing). LÄS MER
5. Reproductive Biology and Population Genetics of Common Ash (Fraxinus excelsior L.)
Sammanfattning : Common Ash, Fraxinus excelsior L. (Oleaceae) is a wind-pollinated, wind-dispersed, deciduous tree, commonly occurring throughout Central and Northern Europe. The thesis addresses several questions concerning reproductive biology and factors influencing the genetic richness of ash stands. LÄS MER
