How can sexual reproduction be manipulated to produce desirable traits in crops?

Genetic recombination can be achieved when the coral colony produces gametes and eventually reproduces; therefore, it is important to provide evidence that ... Bdelloid rotifers, common freshwater invertebrates of ancient origin and worldwide distribution have long been thought to be entirely asexual. What drives the maintenance of sexual reproduction in Eukaryota is a key question in evolutionary biology. Modelling and empirical studies investigating ... During sexual reproduction, two haploid gametes combine into one diploid cell known as a zygote in a process called fertilization. The nuclei from the gametes ... Why does sex -- that is, sexual reproduction -- exist? In many ways, asexual reproduction is a better evolutionary strategy: Only one parent is required, ... Parasitic success without sexual reproduction: what more than 10 years of root-knot nematode genomics revealed? Imprimer; Partager. 31 décembre 2017. Following an overview of the essential details of orchid reproduction, we discuss the evidence that reproductive success (both male and female) is pollination ... Feb 12, 2018 ... Despite odds, fish species that bypasses sexual reproduction is thriving ... An international team of scientists has sequenced the genome of the ... The timing of sex in facultatively sexual organisms is critical to fitness, due to the differing demographic consequences of sexual versus asexual reproduction. Mar 29, 2012 ... Conclusions. We show for the first time that, in the absence of sexual reproduction, female-sterile mutants of M. oryzae rice strains can arise ...
