1. Flowering traits in tetraploid Brachiaria ruziziensis breeding
Abstract Tetraploid Brachiaria ruziziensis genotypes which reproduce sexually are essential for the breeding of other species of the Brachiaria genus which reproduce by apomixis. Aiming at studying the available phenotypic and genetic variability in the breeding population of B. ruziziensis, it was estimated the parameters heritability and genetic and phenot

2. Genetic diversity of American wild rice species
Studies on genetic diversity and genetic structure of natural populations are important in order to define strategies for in situ and ex situ conservation actions and for plant pre-breeding programs. Aiming to assess the genetic diversity and genetic structure of three wild American Oryza species with isozyme markers, 14 populations of the diploid O. glumaep

3. Genetic characterization of the Moxotó goat breed using RAPD markers.
The objective of this study was to verify the genetic diversity between and within seven populations of Moxotó goat (n = 264) from the States of Pernambuco, Paraíba and Rio Grande do Norte, using RAPD (Random Amplified Polymorphic DNA). Moxotó, as well as other naturalized breeds, suffers genetic losses due to the indiscriminate miscegenation with breeds

4. Estimativas de parametros geneticos nas populacoes CMS-42 e CMS-43 de mlho pipoca.
Com os objetivos de elevar a frequencia de alelos favoraveis e estimar os parametros geneticos e fenotipos de algumas caracteristicas agronomicas, as populacoes de milho pipoca CMS-42 e CMS-43 form submetidas ao 2. ciclo de selecao entre e dentro de progenies de meios irmaos. Avaliaram-se 196 progenies de cada populacao, em latice simples 14 x 14, tendo como

5. VariaÃÃo GenÃtica em Aedes aegypti e Aedes albopictus
The invasive mosquitoes Aedes aegypti and Aedes albopictus are world wide important human arboviroses vectors. The Ae. aegypti was introduced in Brazil at 16th century, certainly during the traffic of slavers, while the Ae. albopictus was introduced recently and its distribution is spreading rapidly. These insects show population density variation through th

6. Chromosome Studies in Wild Populations of D. MELANOGASTER
Chromosome studies of wild D. melanogaster populations from Missouri, Mississippi, Louisiana and Texas uncovered 58 inversions. Six were common and cosmopolitan; 52 were new, rare and generally endemic. In one of two Missouri populations tested, structurally heterozygous females carried significantly more sperm at capture than did the homozygotes. In both po
