Partial infertility was observed in the backcross groups (BCP1, BPC1); approximately 3 million larvae developed successfully from 10 billion fertilized eggs, representing a particularly low development rate compared with the bay scallop control (P < 0.
MONITORING HENNEGUYA ICTALURI INFECTION IN CHANNEL CATFISH, BLUE CATFISH AND CHANNEL X BLUE BACKCROSS HYBRIDS USING HISTOPATHOLOGY, REAL-TIME PCR AND IN SITU HYBRIDIZATION
They are known to hybridize and these hybrids then backcross with the parental species leading to introgression, the movement of genes of one species into another.
Also, the hybrids appear to backcross with only one of their parent species,A, cervicornis.
Unfortunately backcross hybrids have lost that heterotic trait.
Indigenous African cattle can be broadly classified into four categories: humpless Bos taurus, humped Bos indicus, sanga (African humpless Bos taurus x humped Bos indicus hybrid), and zenga, defined as sanga x zebu backcross.
lutescens might hybridize and backcross extensively across a zone of secondary contact, and that the population on Kenai is not mainly a mixture of the two parental species, as might be indicated by bimodal distributions (see Jiggins and Mallet 2000).
Evaluation of conventional resistance to European corn borer (Lepidoptera: Crambidae) and western corn rootworm (Coleoptera: Chrysomelidae) in experimental maize lines developed from a backcross breeding program.
Four fish identified as walleye by morphology contained sauger alleles (two backcrosses to walleye, one backcross to sauger, and one [F.
To confirm each backcross, TACF tested the created seedlings by inoculating them with blight.
1] hybrid, as opposed to a backcross or pure parent individual, increases with the number of nuclear loci examined.
Another breeding strategy that is commonly used in inbred mouse studies is the backcross design.
