sterility nghĩa là gì

Ví dụ về sterility

• We propose the hypothesis that some of the same regulatory pathways may be disrupted in the hybrid male sterility of multiple species groups.

• Misexpression of these genes, or genes genetically upstream of them in the regulatory pathway, may contribute to hybrid dysfunctions such as hybrid male sterility.

• Comparisons of both male and female fitness components in all three genotypes might be necessary, especially in populations exhibiting morphological evidence of partial male sterility.

• Inbreeding depression is assumed to be a single, fixed parameter with no differences between sterility genotypes and no evolutionary response to a changing selfing rate.

• The estimates adjusted for this age-related sterility are discussed below.

• This observation could suggest that these genes are downstream targets of the genetic changes that cause hybrid male sterility in these species.

• In the case of sterility, or in many other circumstances, therapeutics accomplishes what nature makes impossible.

• Strikingly, hybrid sterility required having a particular allele at four separate loci - a four-locus epistatic interaction !
